Telekom's Copper Exit: A 1.3 Million-Line Migration Becomes a Cashflow Litmus Test
Published on 08/13/2026 at 14:23 | Redaktion boerse-global.de
The quietest operational shift at Deutsche Telekom may end up saying more about the sustainability of its shareholder returns than any earnings call. The Bonn-based group is moving roughly 1.3 million legacy voice-only landline customers onto LTE-based connections through a new offering dubbed "Call Connect via Funk," a migration that strips copper from the network while keeping customer numbers and handsets intact. Setup takes about 15 minutes per line, according to the company.
The economics are straightforward. Customers can choose between "Call Basic via Funk" at €23 per month with 120 free minutes or "Call Comfort via Funk" at €32.45 per month with a flat rate to German fixed lines, plus either a €3.95 monthly equipment surcharge or a one-off payment of around €100. For the operator, the appeal is equally simple: less copper infrastructure means lower maintenance costs, provided the transition goes smoothly and customers don't resist.
That "provided" is doing a lot of work. The migration lands at a moment when the political climate around network investment has turned contentious. Economy Minister Reiche has signalled a desire to slow infrastructure spending, even as studies from Fraunhofer ISE, Fichtner and EY-Parthenon project substantially higher electricity demand through 2045 than policymakers have assumed. The cost estimate for Germany's network development plan has already climbed from €324 billion in 2023 to €440 billion as of July 2025 — a trajectory that directly shapes how much any operator, including Telekom, will need to spend on the grid of the future.
For investors, the stakes are narrower but sharper. The share repurchase programme that has underpinned the stock's narrative depends on free cash flow, and the LTE migration is an early test of whether management can squeeze more of it out of the fixed-line business. Execute the switch cleanly and the cost base improves, reinforcing the buyback story. Stumble on technical issues or customer pushback — particularly among subscribers in areas with patchy mobile coverage — and the cashflow foundation weakens just as the buyback commitments come due.
Should investors sell immediately? Or is it worth buying Deutsche Telekom?
The market's recent behaviour suggests a wait-and-see posture rather than conviction in either direction. The stock closed Thursday at €28.36, up 0.8 percent on the day after finishing the prior session at €28.14. Over the past seven trading days, however, the shares have shed 2.9 percent — a pullback that follows the announcement of expanded buyback plans roughly a week earlier and the late-July rejection of a merger by T-Mobile US. The recent workforce reductions at the US arm underscore that even the group's most profitable segment faces margin pressure.
The longer-term picture tells a more constructive story. The shares have gained 6.4 percent over the past 30 trading days and are up 2.1 percent year-to-date. The relative strength index sits at 56.6, suggesting room to run without signalling an overheated market. Still, the stock remains 18 percent below its 52-week high of €34.35, reached in late February — a gap that reflects lingering uncertainty about how the pieces fit together.
Analysts, for their part, are not wavering. Six analysts tracked by financial portals all carry buy ratings, with a consensus price target of €38.45. JPMorgan sees the stock at €38.00, Deutsche Bank at €40.00, while UBS and Barclays sit slightly lower at €36.20 and €36.50 respectively. The six-month rating trend is uniformly described as "Buy," implying substantial upside from current levels — a signal that the recent softness is being read as a pause after a strong buyback-driven rally rather than a turning point.
The next concrete checkpoint arrives on October 5, when Telekom hosts an investor day focused on its AI strategy. That event will offer a measure of how credible the cashflow narrative remains. Until then, the migration of 1.3 million telephone lines is a small but telling gauge of operational discipline — and of whether the cost savings that underpin the buyback math will materialise as planned, or get eaten by the friction of moving an ageing customer base onto new technology.
