In Q1 2026, total revenues increased mainly driven by higher service revenues, supported by continued growth in the ICT business and a solid performance in the retail mobile business. Equipment revenues contributed positively to results as well.

Results were primarily driven by the continued strong performance in the CEE region, where all international markets contributed to service revenue growth. This was driven by successful upselling initiatives, an increasing number of fixed-line RGUs in the international markets, and strong growth in the solutions and connectivity business, particularly in Bulgaria. Value-pro-tecting measures were implemented in line with 2025 inflation in Austria (+3.5%, as of April 2026) and Croatia (+3.7% as of March 2026).

In Austria, service revenues declined, resulting in lower total revenues though the decline was partly mitigated by higher equipment revenues.

In a year-on-year comparison, non-operating effects at Group level were broadly unchanged in Q1. There were no one-off effects recorded in Q1. Restructuring charges amounted to EUR 36 mn in both Q1 2026 and Q1 2025. FX effects were negligible with a slight positive FX impact due the appreciation of the Belarusian Ruble versus the Euro.

Total OPEX increased due to higher cost of service and higher cost of equipment. Core OPEX also rose. However, disciplined cost control partially offset product-related cost increases, which were largely driven by licenses and software for resale. Total workforce costs remained stable, reflecting ongoing internal transformation measures. In addition, lower network maintenance costs had a positive effect. Compared to the previous year, the equipment margin improved.

EBITDA increased by 4.6%, with growth in all markets except Austria.

Free cash flow improved by 53.5% in Q1 2026 compared to the same period last year thanks to lower CAPEX and a better operational result.

In April 2026, A1 extended frequencies of 2x25 MHz in the 2.6 GHz FDD band in Austria, with a total investment of approximately EUR 11 mn for the reacquisition of the frequencies.

A1 Group's company SB Telecom established business operations in Dubai, UAE, serving as a sourcing hub for equipment and as a platform for wholesale telecommunications business expansion in the MENA region. This includes data services, voice solutions, roaming and related international connectivity services. This expansion is designed to capitalize on the region's favorable position for international wholesale trade and telecommunications activities.

Mobile subscribers and fixed-line RGUs

In mobile communications, the total number of subscribers increased by 12.5% year-on-year to around 31 million. As in previous quarters, growth was primarily driven by the continued strong expansion of the M2M business. Excluding M2M, the subscriber base increased by 1.8%. Postpaid subscriber growth was recorded across all markets.

In the fixed-line business, the number of revenue generating units (RGUs) increased by 1.9% year on year. While voice RGUs continued to decline, broadband and TV RGUs recorded further growth. Strong RGU growth in the international operations, particularly in Bulgaria and Belarus, more than offset the decline in Austria.

The Internet@home postpaid customer base increased by 6.0% year on year to 4.1 million across the Group. This development reflects both higher broadband RGUs and a rising number of mobile WiFi routers. Broadband RGUs increased in all markets except Austria and Slovenia, while mobile WiFi routers grew in all markets except Croatia and North Macedonia.

Outlook for the financial year 2026

The management board confirms the guidance for total revenue growth of 2-3% compared to the previous year. Capital expenditures excluding frequencies and M&A are expected to amount to around EUR 750 mn.

‌Macroeconomic and Competitive Environment

Compared to the previous quarter, the Austrian economic environment continues to be characterised by subdued growth expectations and easing, albeit still elevated inflation. According to the Austrian National Bank (OeNB), economic growth in Austria

is expected to amount to around 0.5% in 20261), reflecting a modest recovery amid heightened geopolitical uncertainty and higher energy prices. Inflation has declined from the peaks observed in late 2025 but increased again in early 2026. The harmonised inflation rate stood at around 3.1%2) year-on-year in March 2026, following 2.3%3) in February 2026, reflecting renewed upward pressure from energy prices. In this challenging environment, A1 Group continues to navigate macroeconomic head-winds through a customer-centric approach, targeted strategic market investments and stringent cost control.

The telecommunications market in Austria remained highly competitive in the first quarter of 2026. In the mobile market, competitive intensity increased further in the low-value segment, where new providers entered the market with aggressive and competitive offerings. At the same time, the environment in the high-value segment improved slightly. Price increases for new mobile customers were implemented, alongside additional value-protecting measures as outlined above. We responded to ongoing competitive pressure with selective strategic market investments and a focused multi-brand strategy. Price sensitive segments were addressed through targeted initiatives under the brand "YESSS", while high-value customers were approached via the A1 brand through loyalty programs, household bundles and subsidies. The fixed-line market continued to be characterized by high promotional activity and sustained market investments across all players. To defend our position in the Internet@home market, we maintained promotional activity, continued to pursue a technology-agnostic approach and further advanced the fiber roll-out to support upselling. Differentiation was reinforced through additional value-added services such as entertainment and security solutions.

While international markets were also affected by ongoing geopolitical uncertainties, growth dynamics in the CEE region remain stronger than in Austria and the Eurozone in general, reflecting structurally higher growth rates. GDP growth expectations across the region stayed positive. Competitive intensity was broadly stable in the larger CEE markets, and demand for high-speed broadband, ICT solutions and value-added services remained solid.

In Q1 2026, the Belarusian Ruble appreciated against the Euro by 2.5%, with a period average exchange rate of 3.39 in Q1 2026 and 3.47 in Q1 2025.

Revenue development Group revenues increased by 3.9% year on year in the first quarter of 2026. Revenue growth was recorded in all markets except Austria, with particularly strong contributions from Bulgaria, Belarus and Serbia. Equipment revenues increased compared to the prior year. Growth in retail service revenues in the CEE markets more than offset the decline in Austria, with both mobile and fixed retail service revenues increasing across all CEE countries.

Solutions and Connectivity revenues rose by 13% year-on-year, driven largely by ICT deals concluded in Bulgaria.

In Austria, total revenues declined by 2.9%. Higher equipment revenues were not sufficient to compensate for the decline in retail service revenues, which was particularly pronounced in the fixed-line segment. In the mobile business, as in previous quarters, lower incoming ARPU continued to weigh on service revenues, while the customer base was further expanded, with positive net adds both in the core mobile postpaid business and in mobile postpaid WiFi routers.

In the retail fixed-line business, trends remained largely unchanged compared to previous quarters, reflecting continued declines in voice and low-bandwidth customers as well as lower ARPL. At the same time, we continued to record customer growth in the high-bandwidth segment. Solutions and Connectivity revenues remained largely stable. Interconnection revenues declined compared to the previous year, mainly driven by lower network transit volumes. Value-protecting measures were implemented as of April 2026 in the amount of 3.5% based on the CPI for the financial year 2025. (April 2025: 2.9%, April 2024: 7.9%).

A1 Group's international operations delivered a strong financial performance, with total revenues increasing by 10.7% in Q1 2026. Service revenues rose by 11.5% year on year, with growth recorded across all business areas. Equipment revenues also

3) https://tradingeconomics.com/austria/harmonised-inflation-rate-yoy

increased over the same period. Service revenue growth in the international markets was supported by upselling initiatives, strong demand for high-speed broadband products and the continued expansion of ICT solutions.

OPEX and EBITDA

At Group level, total operating expenses increased in Q1 2026, primarily driven by higher cost of service while equipment costs also rose. The rise in Core OPEX was related to ICT deals and cost increases for licenses and software for resale. Total workforce costs remained stable. Restructuring charges amounted to EUR 36 mn in both Q1 2026 and Q1 2025. Overall, we continued our stringent cost control. Savings in network maintenance, commissions and advertising mitigated some of the above-mentioned cost increases.

In Austria, total OPEX declined in Q1 2026 year-on-year. Core OPEX decreased mainly due to lower total workforce costs supported by a lower number of FTEs. Besides that, costs and expenses declined for network maintenance, commissions and advertising. The equipment margin improved year-on-year.

Total OPEX in international markets was driven by higher cost of service. The increase in Core OPEX resulted mainly from the above-mentioned increases for licenses and software for resale. Total workforce costs as well as other product-related costs were also higher. In Belarus, the right-of-use contract for exclusive frequency blocks was cancelled by the Belarusian infrastructure provider beCloud. Starting 2026, the new contract between the provider beCloud and A1 Belarus is exclusively based on used capacities in the 4G network and will be recognized in operating expenses, thus weighing on the OPEX development in a year-on-year comparison.

In Q1, the equipment margin in international markets improved compared to the previous year.

Group EBITDA grew by 4.6% in Q1 2026. Bulgaria, Belarus and Croatia posted the highest contributions on the back of strong service revenue growth and cost control. In Q1, EBITDA grew in all markets except for Austria.

In Austria, EBITDA excluding restructuring declined by 1.9% in Q1 (-2.3% including restructuring). The lower core OPEX as a result of a strong focus on efficiency measures and the improved equipment margin could not compensate for the decline in service revenues.

In international markets, EBITDA increased by 9.6% thanks to service revenue increases in all CEE markets and a high focus on cost control.

Below EBITDA Depreciation and amortization increased due to a different asset mix.

In Q1 2026, EBIT rose by 7.5%. The financial result improved due to higher interest income. Consequently, the period result

rose by 14.7% in Q1 2026.

Capital Expenditures

A1 Group focused on expanding its fiber roll-out and 5G networks both in Austria and internationally. In Q1 2026, capital expenditures ('CAPEX') decreased by 26.3% year-on-year to EUR 164 mn. The decrease was mostly attributable to lower CAPEX in Austria. CAPEX for spectrum was also lower: In Bulgaria, spectrum investments in Q1 2025 amounted to a total of EUR 9.6 mn, while there was no spectrum acquisition in Q1 2026.

In the first quarter of 2026, free cash flow increased by 53.5% year-on-year. Besides the better operational result, the main driver was the lower CAPEX both due to lower investments and lower spectrum payments compared to the same period last year (EUR 10 mn in Q1 2025). Changes in working capital and other changes remained largely stable. Positive effects from accounts payable and lower inventories outweighed a less favourable development in accounts receivable. Overall, that more than offset the higher leases paid.

Balance sheet and net debt

As of March 31, 2026, the total assets amounted to EUR 10,415 mn, 1.8% higher than at December 31, 2025. This was primarily driven by higher cash and cash equivalents. Current liabilities increased mainly due to the increase in accounts payable. Total stockholders' equity rose by 2.7%.

In the first quarter 2026, the increase in cash and cash-equivalents lead to a decline in net debt. Additionally the long-term lease liabilities decreased. Both the 'net debt/EBITDA'-ratio as well as the 'net debt (excl. leases)/EBITDA after leases'-ratio improved.
