EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 5 2Q26 OVERVIEW Kyiv, New York, July 31, 2026 – Kyivstar Group Ltd. (“Kyivstar” or “the Group”), Ukraine’s leading digital operator, today announces financial and operating results for the second quarter ended June 30, 2026. • Total revenue increased 19.3% YoY in 2Q26 to USD 339 mn (UAH 14.9 bn, +27.0%). This was driven by sustained revenue generation across the telecommunication subscriber base, progress across digital platforms, and the acquisition of Tabletki.ua (“Tabletki”), which further broadened the Group’s digital ecosystem. • Telecommunications and infrastructure revenue rose 8.8% YoY in 2Q26 to USD 265 mn (UAH 11.7 bn, +15.8%). Growth was driven by rising mobile ARPU and data consumption, and an expanding fixed broadband customer base. The telecommunications and infrastructure vertical includes revenue from the solar power plants acquired between December 2025 and May 2026. • Digital revenue rose 83.0% YoY in 2Q26 to USD 73.7 mn (UAH 3.3 bn, +94.7%) on the back of Uklon (mobility platform, acquired effective April 2025), Tabletki (online pharmaceutical platform, acquired effective February 2026), and growth across other verticals. Digital reached 21.7% of total revenue for 2Q26. • The Group recorded a net profit of USD 77 mn for 2Q26, with earnings per share of USD 0.33, inclusive of a USD 21.2 mn non-cash charge from the 2Q26 fair value change on outstanding KGL warrants. • EBITDA rose 13.7% YoY in 2Q26 to USD 188 mn (UAH 8.3 bn, +21.1%), producing a 55.4% margin. The EBITDA margin for the Telecommunications and infrastructure business was 59.1%, and 42.0% for the digital business. • Kyivstar served 21.8 mn mobile customers and 1.3 mn fixed broadband customers as of June 30, 2026. Mobile ARPU increased 11.2% YoY to USD 3.9 (UAH 172.7, +18.3%) for 2Q26. Multiplay customers were stable QoQ at 8.1 mn (+23.6% YoY) with their ARPU increasing 15.6% YoY. They represented 39.9% of one‑month‑active mobile customers as of June 30, 2026. • Group digital customers stood at 29.3 mn (+3.0% QoQ). Uklon reached 5.2 mn customers and recorded 43.0 mn rides and 1.4 mn deliveries in 2Q26. Tabletki recorded 15 mn average monthly bookings in 2Q26 and processed gross merchandise value (GMV) of USD 376 mn for the quarter. • Capital expenditures excluding licenses and ROU totaled USD 59 mn (UAH 2.6 bn), with capex intensity of 26.6% for the last 12 months and 17.3% for 2Q26, reflecting investments in network resilience and targeted reinvestment. • Kyivstar maintained a strong balance sheet with USD 364 mn of cash and cash equivalents as of June 30, 2026. • Kyivstar continued to advance its strategic priorities. Key developments during the quarter include expanding Starlink satellite connectivity; the solar plant acquisition and its implied cost hedge; Uklon’s expansion into commerce, multimodal mobility and autonomous driving; and a series of milestones advancing the development of Ukrainian AI infrastructure. • Kyivstar is raising its 2026 financial outlook to reflect robust growth momentum. The Group now expects USD revenue growth of 14%-16% (prior: 11%-14%) and EBITDA growth of 9%-12% (prior: 7%-10%). This reflects UAH revenue growth of 21%-23% (prior: 18%-21%) and UAH EBITDA growth of 17%-19% (prior: 14%-17%) at an assumed average UAH/USD rate of 44.5 for 2026.

Uklon continues to progress in its evolution into a one-stop mobility platform. Developments in 2Q26 include: • An agreement to acquire E-wings, adding electric scooters to its mobility platform and expanding Uklon beyond ride-hailing into multimodal urban transport across 11 Ukrainian cities. • The launch of the Uklon Travel booking solution for domestic and multinational bus routes and accompanying Uklon Travel Bus with co-branded routes to key travel hubs. All of Ukraine remains a no-fly zone due to the war, placing extra emphasis on the role of buses in the economy and the country’s public transportation network. • Ukraine’s first live testing of autonomous vehicle technology, positioning Uklon as Ukraine’s leader in the autonomous mobility and robotaxi space. • The launch of Uklon Store, marking Uklon’s first move beyond mobility into a broader in-app commerce platform. Starting with same-day flower delivery in Kyiv, the service builds on Uklon’s 5.2 mn active users.

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 11 The launch deepens customer engagement and opens new digital revenue streams beyond mobility. Helsi: focused on growing the premium subscription base Helsi is Ukraine’s leading health-tech platform, providing 5.0 mn customers (+1.7% QoQ) as of 2Q26 with B2C, software-as-a-service, and data-driven healthcare services. Revenue for 2Q26 rose 35.9% YoY to USD 2.4 mn (44.6% to UAH 105 mn). Customers paying for premium services (premium subscriptions) grew to more than 109,000 by end 2Q26, up from 57,000 at end 2025 and 87,000 at end 1Q26. Growth continues to be driven by family and individual medical care subscription plans, along with growing adoption of detailed health insight products, including automatic interpretation of medical test results and biomarker tracking. The Helsi Superpower bundle, which extends Helsi’s advanced digital health features to Kyivstar mobile subscribers, maintains meaningful traction and has become a core driver of conversion to paying customers, further strengthening cross-ecosystem synergies. Helsi is deeply embedded in Ukraine's eHealth ecosystem, powering appointment scheduling, prescriptions, and health records management. This deep integration, including touchpoints with systems like accounting and insurance processing, makes Helsi indispensable for both patients and providers alike. The vertical also aligns closely with public policy goals regarding digital healthcare initiatives, in turn reflecting Kyivstar’s commitment to ESG and CSR. As of June 30, 2026, Kyivstar customers were able to access more than 1,700 public and private clinics and nearly 44,000 medical professionals. Patients made more than 2.4 mn appointments through Helsi in 2Q26. Tabletki: Strong quarter, progressing ecosystem ties Tabletki is Ukraine’s leading online marketplace for pharmaceuticals and healthcare products, facilitating search, comparison, inventory verification, and purchases at more than 14,500 Ukrainian pharmacies. Tabletki was consolidated effective February 2026 and contributed UAH 342 mn (USD 7.8 mn) in revenue and UAH 274 mn (USD 6.2 mn) in EBITDA in 2Q26. Gross merchandise value (GMV) of bookings completed through the platform amounted to UAH 16.6 bn for 2Q26, while number of orders reached 44.9 mn. Tabletki recognizes revenue from the commission and service fees earned rather than the gross value of transactions facilitated through its platform.

The teams are focused on creating a seamless patient journey across healthcare services and pharmaceutical purchases. This includes mutual lead generation, telemedicine integration, ordering of medicines under prescription, and advanced data analytics. Optimizing synergies across Helsi’s platform with Tabletki’s leading position in pharmaceutical search and discovery is expected to strengthen the group’s ability to build a fully integrated digital health ecosystem.

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 12 Kyivstar TV: Steady upward customer engagement Kyivstar TV is the largest streaming service by customer base in Ukraine. The number of customers grew 4.4% QoQ in 2Q26 to 3.6 mn. As of June 30, 2026, 49.2% of the Group’s broadband customers were also digital TV customers, reflecting the synergies across both services. Revenue reached USD 13.9 mn (UAH 614 mn) in 2Q26, a more than fivefold increase YoY in large part due to the change to the service’s revenue model from September 2025. The service engages customers on a wide range of platforms, including OTT, and is accessible by design to potential customers regardless of whether they are already part of the Kyivstar ecosystem. Exclusive, high-visibility content targeting a Ukrainian audience promotes customer acquisition and visibility, including most recently rights to broadcast Ukrainian and world boxing champion Oleksandr Usyk’s May bout with Rico Verhoeven and action thriller Killhaus – in addition to an expansive library of other Ukrainian and global content. Digital Enterprise: Building Momentum Digital Enterprise encompasses a diverse range of offerings that mostly target B2B customers, including SMEs. Revenue grew 15.8% YoY in 2Q26 to reach USD 16.9 mn (+23.2% YoY to UAH 746 mn). Active contracts grew 29.4% YoY to 2.4k in 2Q26. The Big Data and AI business generated revenue of USD 5.5 mn in 2Q26, +96.9% YoY (84.8% to UAH 242.9 mn), supported by continued AdTech enhancements, analytics growth, and AI‑driven customer engagement. The Adwisor self-service AdTech platform had over 4,100 registered clients as of June 2026. The cloud business sustained strong momentum with 34.2% YoY revenue growth to USD 2.3 mn (+42.8%YoY to UAH 103.3 mn), underpinned by renewed Microsoft partner designations, expanded cybersecurity partnerships, and closer regional integration within the VEON Group, altogether reinforcing Kyivstar’s position as a trusted cloud and digital transformation partner. Identity and credential management services saw revenue decline in 2Q26 by 9.1% to USD 8.9 mn (-3.3% YoY to UAH 394.4 mn) as a result of the continuing technological shifts. Development continues apace on the Syaivo national LLM initiative. Model 4B entered beta testing and reached the top position on the Ukrainian leaderboard among smaller models. Kyivstar also signed a Memorandum of Understanding with Ukraine’s Ministry of Economy in June 2026 to explore expanded cooperation in sovereign AI infrastructure. The initiative aims to strengthen digital resilience and technological sovereignty, including supporting scalable AI adoption across public services, financial services, industry, and research. Capital expenditure Capex excluding licenses and right-of-use for 2Q26 was USD 59 mn (UAH 2.6 bn) with a capex intensity of 17.3%. Intensity for the last twelve months to end 2Q26 was 26.6%. The capex intensity underscores Kyivstar’s commitment to investments that sustain network quality and resilience amid the war. • Capex focus: Continued investment in network resilience, fiber rollout, and energy security remains a top priority, even as total CAPEX declined year-over-year (2Q26 -29.4%, 1H26 -6.0%). • Energy resilience: Kyivstar’s network sites are now equipped with backup batteries, inverters and solar power, reducing vulnerability to grid instability and proceeding in line with contemporary legal requirements. Kyivstar will continue to comply on this matter, inclusive of any new regulatory requirements that may come into force going forward. As of June 2026, the Group had funded the installation of more than 10,200 generators (stationary diesel generators, mobile diesel generators and third-party stationary diesel generators) and over 260,000 additional batteries for backup capacity and improved network resilience.

Revenue from enterprise identity and credential management services has been reported within the Digital Enterprise vertical from 1Q26 (USD 9.7 mn) onward and 2Q26 (USD 8.9mn). Prior periods have been reclassified accordingly (1Q25 USD 11.0 mn and USD 9.8 mn). 2. See Attachment A for reconciliations to Kyivstar’s non-IFRS measures and Attachment D for a detailed description of such measures. 3. Profit and EPS also reflect USD 21.2 mn fair value loss on KGL warrants in 2Q26 and USD 22 mn in 1H26. Total revenue growth of 19.3% for 2Q26 reflects rising mobile ARPU and data consumption, along with boosts from an expanding fixed broadband customer base and the diversification into renewable energy. EBITDA growth of 13.7% for 2Q26 was driven by revenue growth, acquisitions, operating leverage, and disciplined cost management. To provide greater visibility into our evolving business mix, Kyivstar’s EBITDA margin for our core Telecommunication and infrastructure declined 1.4 p.p. YoY to 59.1%, while our digital business margin stood at 42.0% for 2Q26. The overall EBITDA margin declined by 2.7 p.p. YoY to 55.4% for the quarter, reflecting the scaling of these high-growth, relatively lower-margin digital platforms. While digital businesses produce lower EBITDA margins than traditional Telecommunication services due to their growth and investment characteristics, their lower capital intensity supports strong free cash flow conversion and cash generation comparable to Telecommunication businesses. Depreciation and amortization increased 24.3% for 2Q26, reflecting sustained investment in network capacity, spectrum-related assets, digital platforms and IT infrastructure, as well as the timing of recent capex entering the depreciation cycle. Operating profit (EBIT) increased 13.6% for 2Q26, supported by the higher EBITDA and consolidation of Tabletki and solar power plants, and partly offset by the higher depreciation and amortization costs. Net-finance costs were largely stable YoY in 2Q26. These reflect the net impact of interest on lease liabilities, interest expenses on payables to VEON and interest income on cash balances. Other non-operating loss was primarily driven by change in fair value of outstanding warrants (USD -21.2 mn for 2Q26). Foreign exchange gain was driven by a smaller revaluation gain in 2Q26 on the Group's net foreign-currency position. Income tax expense declined 5.3% in 2Q26, mainly driven by the lower profit before tax. The effective tax rate

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 14 remained broadly stable YoY to 20.5% for 2Q26 (from 20.4% in 2Q25).

Lease liabilities associated with towers transferred to Ukraine Tower Company are fully recognized under IFRS 16.

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 15 STRATEGIC DEVELOPMENTS Kyivstar’s work with Space X’s Starlink continues to develop. More than 6 mn Kyivstar customers have now used the direct to cell (D2C) service, which has expanded beyond messaging to incorporate data with select apps even when there is no terrestrial signal, starting with Google Maps, Viber and WhatsApp. Kyivstar completed the acquisition of six solar power plants in Ukraine’s Lviv region, with a combined installed capacity of 105 MW, for USD 80.8 million, comprising purchase consideration of approximately USD 69.8 million paid to the sellers and an additional approximately USD 11 million of reimbursable financial assistance provided by Kyivstar to the target companies to refinance existing bank indebtedness. The transaction expanded Kyivstar’s total solar-generation capacity to 118 MW, with expected annual output equivalent to approximately 30% of Kyivstar’s current annual electricity consumption across its telecommunication operations. Uklon launched Uklon Store, marking its first move beyond mobility into a broader in-app commerce platform. Starting with same-day flower delivery in Kyiv, the service builds on Uklon’s 5.2 mn active users. The launch deepens customer engagement and opens new digital revenue streams beyond mobility. Uklon also announced an agreement to acquire E-wings, adding electric scooters to its mobility platform, and expanding Uklon beyond ride- hailing into multimodal urban transport across 11 Ukrainian cities. Separately, Uklon launched Ukraine’s first live testing of autonomous vehicle technology during the quarter, positioning Uklon as the leader in Ukraine’s autonomous mobility and robotaxi space. In June, Kyivstar signed an MoU with Ukraine’s Ministry of Economy to explore an AI-ready data center in Ukraine, supported by VEON’s financial capacity and global expertise. The initiative would expand secure in-country computing capacity, strengthen digital resilience and technological sovereignty, and support scalable AI adoption across public services, financial services, industry and research. Any investment would be phased within Kyivstar’s existing capital expenditure framework, supporting Ukraine’s long-term digital growth while maintaining disciplined capital allocation. Also in June, Kyivstar signed an MoU with Ukraine’s National Securities and Stock Market Commission to explore mechanisms to enable investors in Ukraine to access Kyivstar’s existing Nasdaq-listed shares through established brokerage channels. The initiative aims to broaden domestic participation in Kyivstar’s growth, strengthen Ukraine’s capital markets, and deepen their integration within the global financial system. The parties will assess the regulatory, legal and operational framework required to advance the initiative in compliance with Ukrainian and U.S. securities laws.

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 16 OUTLOOK FOR 2026 For 2026, Kyivstar has revised its outlook and now expects to deliver revenue growth of 21%-23% and EBITDA growth of 17%-19% YoY in UAH terms. In USD terms (assuming UAH/USD averaging 44.5 for the year), revenue is expected to grow 14%-16% and EBITDA by 9%-12%. Capex intensity for 2026 is unchanged and expected to reach 21%-24% of revenue.

The outlook is subject to risks and uncertainties including, but not limited to, those discussed herein. Actual outcomes may differ materially from current expectations, and current expectations should not be construed as a guarantee of future performance and are provided for informational purposes only. The Group’s outlook includes IFRS and non-IFRS financial measures, where reconciliation is impossible without unreasonable effort due to the inherent difficulty in forecasting certain items that are dependent on future events and circumstances beyond the Group’s control. Such items may be material. 2. U.S. dollar expectations assume an average 2026 exchange rate of UAH 44.5 per U.S. dollar. We cannot provide a reconciliation of the non-IFRS measures EBITDA and capex intensity projections for 2026 without unreasonable effort, given that we are unable to estimate the amounts of certain components of the IFRS profit / (loss) for the period, including income taxes and net gain / (loss) on foreign exchange, and IFRS intangible assets and certain costs which impact the IFRS property, plant and equipment. Due to the nature of certain reconciling items, it is not possible to predict with any reliability what future outcomes may be regarding the expense or income that may ultimately be recognized in 2026. We present certain financial information with respect to Kyivstar Group and certain of its operating companies in local currency terms. This non-IFRS financial measure is intended to present the results of Kyivstar Group in local currency amounts and thus exclude the impact of translating such local currency amounts to our reporting currency, U.S. dollars, improving the comparability of results between periods. Our management believes that this increase in comparability between periods provides an additional and meaningful assessment of performance to our management and to investors. This non-IFRS financial measure should not be considered in isolation from, or as a substitute for the Group’s audited financial statements as reported under IFRS. For information regarding our translation of foreign currency-denominated amounts into U.S. dollars, please refer to Attachment C of this document.

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 21 Attachment A: Reconciliation tables Management believes that the below non-IFRS measures are useful to investors in evaluating our operating performance.

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 28 Attachment D: Definitions 4G customers 4G customers are mobile customers who used fourth-generation (4G or LTE) network technologies during the three months prior to the measurement date. ARPU (average revenue per user/customer) measures the monthly average revenue per mobile customer. We generally calculate ARPU by dividing our mobile telecommunication and digital service revenue generated by our own subscribers during the relevant period by the average number of our mobile customers during the period and the number of months in that period. Telecommunication revenue includes all mobile connectivity-related revenue, exclusive of revenue from device sales, while digital revenue is limited to revenue from mobile and web digital platforms. Capital expenditures (capex) is a non-IFRS financial measure and is defined as capex excluding licenses and ROU as purchases of property, plant and equipment and intangible assets, after deducting additions in licenses and right-of-use assets. Capex intensity is a ratio that is calculated as last-twelve-month (LTM) capex excluding licenses and ROU divided by LTM total revenue. Digital customers include gross total cumulative users for the reported period of all digital platforms, services and applications offered by an entity or by the Group and include users who are active in more than one application. Digital revenue includes digital services and platforms, spanning entertainment (gaming, music, and video streaming), e-commerce, ride-hailing, super apps. It also includes enterprise solutions such as credential management services as well as digital offerings in health. Digital EBITDA represents the portion of EBITDA generated from Kyivstar Group Ltd’s digital services and platforms. Digital EBITDA is calculated by applying the definition of EBITDA to the results of operations attributable to these digital services and platforms. EBITDA is a non-IFRS financial measure and is called Adjusted EBITDA. Adjusted EBITDA is a non-IFRS financial measure. Adjusted EBITDA should not be considered in isolation or as a substitute for analyses of the results as reported under IFRS. We calculate Adjusted EBITDA as profit/(loss) for the period, before impairment loss, financial expenses and costs, net foreign exchange gain/(loss), share of profit/(loss) of associates and joint ventures, and listing expense, which is also excluded from the calculation. EBITDA margin is calculated as EBITDA (as defined above) divided by total revenue, expressed as a percentage. EBITDA after leases (EBITDAaL) is calculated as EBITDA (as defined above) after lease expense. Equity free cash flow (before leases and licenses) is a non-IFRS measure and is defined as free cash flow from operating activities and proceeds from sale of non-current assets, less cash flow used in investing activities. Equity free cash flow (after leases and licenses) is a non-IFRS measure and is defined as free cash flow from operating activities and proceeds from sale of business, less cash flow used in investing activities, excluding license payments, lease payments, cash outflows for business acquisitions, inflow/outflow of deposits, and financial assets, cash inflows from sale of business and proceeds from share issuance. Gross debt is calculated as the sum of long-term notional debt and short-term notional debt, including capitalized leases. Gross merchandise value (GMV) is calculated as total monetary value of goods or services facilitated through the platform over a given period, before deducting commissions, fees, discounts, refunds, or costs. Mobile customers (also mobile subscribers) are generally customers in the registered customer base at a given measurement date who engaged in a mobile revenue generating activity at any time during the three months prior to such measurement date. Such activity includes any outgoing calls, customer fee accruals, debits related

EARNINGS RELEASE & OPERATING HIGHLIGHTS 2Q26 & 1H26 29 to service, outgoing SMS and MMS, data transmission and receipt sessions, but does not include incoming calls, SMS and MMS or abandoned calls. The Group’s total number of mobile customers also includes customers using mobile internet service via USB modems and fixed-mobile convergence (“FMC”). Multiplay customers are customers who also used one or more of Kyivstar’s digital products at any time during the one month prior to such measurement date. Effective 2Q25, 4G usage below the 100 MB threshold is included in Multiplay and Double Play 4G customer count (excluded prior to 2Q25). Net debt is a non-IFRS financial measure and is calculated as the sum of interest-bearing long-term debt, including capitalized leases (unless specifically excluded) and short-term notional debt minus cash and cash equivalents including deposits, long-term and short-term deposits (deposits of USD 0.6 mn, UAH 27 mn as of June 2026). Kyivstar believes that net debt provides useful information to investors because it shows the amount of notional debt that would be outstanding if available cash and cash equivalents including deposits, long-term and short-term deposits were applied to repay such indebtedness. Net debt should not be considered in isolation as an alternative to long-term debt and short-term debt, or any other measure of the Group’s financial position. Revenue from telecommunication services and from infrastructure (“telecom and infrastructure revenue” or “telecom and infra revenue”) is revenue generated by Kyivstar Group Ltd from providing telecommunication services and infrastructure services. Telecommunication services refer to fixed and mobile voice, data, interconnection, roaming, messaging, and value-added services. Infrastructure services primarily relate to energy infrastructure assets, primarily solar energy solutions owned by KGL, with electricity supplied to the national energy grid in accordance with applicable market and regulatory frameworks. EBITDA from telecommunication services and from infrastructure (“telecom and infrastructure EBITDA” or “telecom and infra EBITDA”) represents the portion of EBITDA generated by Kyivstar Group Ltd from providing telecommunication and infrastructure operations. Telecom/infra EBITDA is calculated by applying the definition of EBITDA to the results of these Telecommunication and infrastructure activities.
