Disclosure of the total of all fiber-optic lines (FTTx).

Total

In Germany, we continue to be market leader both in terms of fixed-network and mobile revenues. This success is attributable to our high-performance networks, a broad product portfolio, and good service. We want to offer our customers a seamless and technology-neutral telecommunications experience. We regularly adapt our product portfolio to address the needs of our customers.

Mobile communications

Our Germany operating segment had a total of 71.1 million mobile customers as of June 30, 2025. The number of high-value mobile contract customers under the Telekom and congstar brands grew by 459 thousand customers overall against December 31, 2024. Sustained high demand for mobile rate plans with data volumes continues to drive this trend. The prepaid customer base grew by 4.9 % against the end of 2024, driven in particular by the M2M SIM cards used in the automotive industry.

Fixed network

Demand for our fiber optic-based lines has risen slightly since the end of 2024, with the total number of lines growing to 20.9 million. This growth is driven by demand for higher bandwidths.

The number of retail broadband lines remained more or less stable against the end of 2024 at a total of 15.1 million customers. Around 53 % of the customers have subscribed to a rate plan with speeds of 100 Mbit/s or higher. The rise in demand for our TV content drove growth in our TV customer base of 60 thousand against year-end 2024, an increase of 1.3 %. The number of fixed-network lines stood at 17.0 million.

Wholesale

As of June 30, 2025, fiber-optic-based wholesale broadband lines accounted for 74.1 % of all lines – an increase of 1.6 percentage points against the end of 2024. This growth is a result of the demand for our commitment agreements. Ongoing demand among retail customers for higher-bandwidth lines also contributed to the increase. The number of unbundled local loop lines decreased by 182 thousand compared with the end of the prior year, while fiber-optic-based wholesale broadband lines increased by 15 thousand. These developments result partly from the shift to higher-value fiber-optic-based lines and partly from consumers switching to other providers. In addition, our wholesale partners are migrating their retail customers to their own infrastructures. The total number of wholesale lines at June 30, 2025 was 10.3 million.

Revenue, service revenue

Total revenue in our Germany operating segment decreased in the first half of 2025 by 1.3 % year-on-year to EUR 12.5 billion, driven mainly by lower mobile terminal equipment revenues. By contrast, service revenues grew by 1.2 % year-on-year, due to growth in the mobile and fixed-network businesses, largely driven by broadband and TV business.

Revenue from Consumers declined by 2.2 % year-on-year due to lower mobile terminal equipment revenue. The fixed-network business continued to perform well, characterized by sustained broadband revenue growth driven by a number of positive factors, including customer appreciation for reliable networks and high bandwidths as well as our TV offerings. This development more than offset the decline in voice components. Mobile service revenues also trended positively, in line with customer development.

Revenue from Business Customers remained on a par with the prior-year period, mainly as a result of the performance of the mobile business. The fixed-network business remained stable.

Wholesale revenue remained stable year-on-year in the first half of 2025 at EUR 1.6 billion.

Adjusted EBITDA AL, EBITDA AL

Adjusted EBITDA AL increased by EUR 0.1 billion or 2.1 % year-on-year. The main reasons for this increase are high-value service revenue growth and enhanced cost efficiency, primarily as a result of the lower headcount and the ongoing implementation of efficiency enhancement and digitalization measures. Various one-time effects came into play. Our adjusted EBITDA AL margin amounted to 41.9 %.

At EUR 5.1 billion, EBITDA AL increased by 7.3 % against the prior-year period, due to the effects described under adjusted EBITDA AL and lower year-on-year expenses arising from special factors. Special factors in the first half of 2025 amounted to EUR 0.2 billion, and mainly related to socially responsible staff restructuring measures.

Profit/loss from operations (EBIT)

Profit from operations amounted to EUR 3.2 billion, an increase of 10.6 % against the prior-year period. The positive EBITDA trend in particular contributed to this development. This was offset by an increase of 2.1 % in depreciation, amortization and impairment losses, mainly resulting from rising fiber build-out volumes.

Cash capex (before spectrum investment), cash capex

Cash capex (before spectrum investment) decreased by EUR 292 million or 11.4 % compared with the prior-year period, primarily due to the intra-year allocation of investments in the fiber build-out. The number of households passed by our fiber-optic network increased to 11.1 million by the end of the first half of 2025. In mobile communications, 98.7 % of German households can already use 5G.

5G
Refers to the mobile communications standard launched in 2020, which offers data rates in the gigabit range, mainly over the 3.6 GHz and 2.1 GHz bands, converges fixed-network and mobile communications, and supports the Internet of Things.
Glossary
AL – After Leases
Since the start of the 2019 financial year, we have taken the effects of the first-time application of IFRS 16 “Leases” into account when determining our financial performance indicators. “EBITDA after leases” (EBITDA AL) is calculated by adjusting EBITDA for depreciation of the right-of-use assets and for interest expenses on recognized lease liabilities. When determining “free cash flow after leases” (free cash flow AL), free cash flow is adjusted for the repayment of lease liabilities.
Glossary
Fixed-network lines
Lines in operation excluding internal use and public telecommunications, including IP-based lines. The totals reported in the combined management report were calculated on the basis of precise figures and rounded to millions or thousands. Percentages were calculated on the basis of the figures shown.
Glossary
M2M – Machine to Machine
Communication between machines. The information is automatically sent to the recipient. For example, in an emergency, alarm systems automatically send a signal to security or the police.
Glossary
Mobile customers
In the combined management report, one mobile communications card corresponds to one customer. The totals were calculated on the basis of precise figures and rounded to millions or thousands. Percentages were calculated on the basis of the figures shown (see also SIM card).
Glossary
Prepaid
In contrast to postpaid contracts, prepaid communication services are services for which credit has been purchased in advance with no fixed-term contractual obligations.
Glossary
Retail
The sale of goods and services to end users. By contrast, the business with wholesale services for other telecommunications companies is referred to as wholesale business.
Glossary
SIM card – Subscriber Identification Module card
Chip card that is inserted into a cell phone to identify it in the mobile network. Deutsche Telekom counts its customers by the number of SIM cards activated and not churned. Customer totals also include the SIM cards with which machines can communicate automatically with one another (M2M cards). The churn rate is determined and reported based on the local markets of the respective countries.
Glossary
ULL – Unbundled Local Loop
Competitors whose own networks do not reach into customers’ premises can rent unbundled local loop lines from Deutsche Telekom. Their networks end at the local exchanges. The ULL bridges the distance between the local exchange and the termination point on the customer’s premises or in their home, so it is also known as the “last mile.”
Glossary
Wholesale
Refers to the business of selling services to telecommunications companies which sell them to their own retail customers either directly or after further processing.
