Telekom's Copper-Phaseout Conundrum: A Giant Caught Between Modernisation and Multiple Headwinds
Published on 08/29/2026 at 04:31 | Editorial boerse-global.de
The numbers tell a story of operational resilience. The share price tells a story of caution. And the legal calendar tells a story that won't be resolved for another two years. Deutsche Telekom finds itself squeezed between all three narratives as it navigates one of its most complex periods since the T-Mobile US merger reshaped its balance sheet.
At the heart of investor unease sits a sprawling shareholder lawsuit stemming from the 2020 Sprint acquisition. The Delaware Court of Chancery has now pencilled in trial dates for October 2027, with damages claims ranging from $3.6 billion to $10.1 billion — a spread wide enough to make even the most sanguine portfolio manager pause. While the hearing remains distant, legal proceedings of this magnitude have a habit of triggering valuation discounts long before any verdict lands.
The Copper Switch-Off
Meanwhile, the company is preparing to uproot a slice of its legacy customer base. Roughly 1.3 million pure fixed-line subscribers — the so-called "sleepers" who have never migrated beyond traditional copper connections — will be notified that their technology is being retired by the end of 2028. The proposed alternative: mobile-based tariffs that reportedly carry heftier price tags than existing contracts.
For shareholders, the calculus cuts both ways. The migration accelerates network modernisation and aligns with the broader strategic push into fibre infrastructure, including the recently announced buildout in Frankfurt (Oder) and community outreach sessions in municipalities like Elsteraue. But it also risks alienating a customer segment that may simply defect to competitors rather than pay more for a service they already receive.
The fibre ambitions extend well beyond German borders. The acquisition of Polish broadband operators Fiberhost and Inea from Macquarie Asset Management — a deal valued at roughly €1 billion — positions T-Mobile Polska as a converged player in a market where the company sees meaningful growth potential.
A Security Scare With Long Tentacles
Adding to the reputational pressure is a vulnerability uncovered in VoLTE calling across German mobile networks. Security researchers found that device identifiers such as IMEI numbers could be inadvertently transmitted to callers. The flaw, brought to light by Bavarian public broadcaster BR and flagged as relevant by the Federal Office for the Protection of the Constitution, strikes at the heart of what network operators sell: trust. The Telekom has already implemented network changes in August to stem the data leakage, but regulatory assessments remain open-ended, and reputational damage is notoriously difficult to quantify in a balance sheet.
As Deutsche Telekom works to rebuild trust around its network security, businesses face their own reputational risks when safety documentation falls short. Many UK employers unknowingly leave gaps in their workplace risk assessments — gaps that can surface painfully during an inspection or after an incident.

Analyst Divergence
The mixed signals have produced a rare split among the analyst community. Kepler Cheuvreux downgraded the stock from "Buy" to "Hold" on Wednesday, trimming its price target from €35 to €32 with explicit reference to the VoLTE vulnerability and intensifying competition at T-Mobile US. The cautious stance was reinforced by second-quarter figures that showed revenue climbing 4.4 percent to €29.93 billion while earnings per share slipped from €0.54 to €0.51 year-on-year — a divergence between top-line growth and bottom-line performance that rarely goes unnoticed.
Yet Zacks Research moved in the opposite direction on Thursday, upgrading the American Depositary Receipts to "Zacks Rank #2 (Buy)" on the back of optimistic earnings forecasts. The conflicting verdicts capture the broader uncertainty surrounding the stock.
The Bull Case
Optimists point to fundamentals that remain sturdy. Organic revenue growth hit 3.3 percent in the second quarter, with adjusted EBITDA AL up 7.3 percent. Free cash flow guidance for 2026 has been nudged higher to approximately €20 billion, while adjusted EBITDA AL is projected to hold around €47.5 billion. The ongoing share buyback programme adds another layer of support.
T-Mobile US has also signalled that it will not pursue merger plans with the parent company, removing a persistent source of structural ambiguity from the equation. If the Sprint litigation can be treated as a distant risk until 2027, the market may well focus on the buybacks and the growth trajectory.
The Bear Case
The bearish argument rests on the compounding effect of uncertainty. Even at the lower end of the damages range, an adverse ruling in Delaware would represent a substantial hit. And while the trial date is far off, interim rulings and newly surfaced details can reset market perception at any moment. The VoLTE affair adds a second, less quantifiable layer of risk that defies conventional valuation models.
The price action reflects the tension. The stock closed Friday at €28.52, up 1.4 percent on the day, but the longer-term picture is less flattering: a 9.1 percent decline over twelve months and a share price still trading roughly 17 percent below its 52-week high of €34.35, reached in late February. Over the past month, the shares have managed a 4.1 percent improvement, though the weekly performance showed a 1.2 percent dip.
What Comes Next
Two dates now dominate the calendar. On 5 October, the company hosts its AI investor day; on 5 November, third-quarter results will be published. Both events offer opportunities to demonstrate whether operational momentum can continue to outshine the legal and reputational shadows — or whether the cautious tone adopted by Kepler Cheuvreux proves to be the opening salvo in a broader reassessment.
