Deutsche Telekom AG (DTEGY)

How it makes money

Most revenue is recurring subscription fees for network access, billed monthly regardless of how much a customer actually uses. Building and upgrading the underlying networks — spectrum, fibre, towers — requires continuous heavy capital spending, so profitability depends on spreading that fixed cost over as many paying subscribers as possible; the U.S. business, T-Mobile, is now the largest single contributor to group revenue.

Revenue by segment

Owning nationwide spectrum licences and physical network infrastructure is expensive enough to keep out most new entrants, and customers rarely switch carriers over small price differences once installed. But the advantage is not exclusive: a handful of well-capitalized rivals own comparable networks in every market Deutsche Telekom serves, so competition still pressures prices.

Mobile and broadband access are close to essential services for most households and businesses, so subscriber numbers hold up reasonably well even in a weaker economy. Growth instead comes mainly from price increases, added services and subscriber gains in the U.S. market rather than from the economic cycle.

Key risks

• Intense competition in the U.S. market — T-Mobile US operates in a market the company describes as intensively competitive, with potential saturation of wireless customer growth and increasing convergence among mobile, fixed-network and satellite providers.
• Data privacy and cybersecurity — The company ranks data privacy and security as its highest-significance operational risk, citing GDPR exposure with potential fines of up to 2-4% of total worldwide annual revenue alongside evolving cyber threats.
• German and European market competition — Intensifying competition and uncertain economic conditions across consumer, business and wholesale segments in Germany have raised this risk from low to medium significance.
• Procurement and supplier disruption — The company raised this risk from medium to high significance, citing geopolitical disruption, component shortages, supplier concentration and the pass-through cost of U.S. tariffs.
