Earnings call transcript: 1&1 AG Q1 2026 sees modest revenue growth

1&1 AG reported Q1 2026 revenue of EUR 1.146 billion, up 1.1% year over year and slightly above forecast, while net profit rose 60.4% to EUR 17.8 million. The offset was a 6.8% decline in gross profit and a 1.69% share-price drop as higher national roaming costs and softer service revenues weighed on sentiment. Management reiterated 2026 EBITDA guidance of about EUR 800 million and said mobile and broadband growth should improve as the network buildout and pricing actions progress.

Analysis

The market is reacting as if this is a clean telco margin miss, but the deeper issue is mix and timing: the earnings power is migrating from legacy service economics toward a network build that only pays off once coverage inflects. That creates a temporary “investment valley” where reported gross margin can lag even while the operating model improves, which is why the print can look healthy on profit yet still trade poorly. The key second-order effect is that every increment of self-traffic should reduce external roaming leakage with a lag, so the real earnings step-up is more likely in the back half of 2026 into 2027 than in the next quarter.

Competition is the more important catalyst than the current quarter. Management’s willingness to lift prices implies the group is choosing ARPU discipline over near-term volume, which should stabilize economics if peers stay rational; if not, mobile net adds could wobble for 1-2 quarters and the market will likely penalize the stock again. In fixed line, broader wholesale access is the hidden lever: once more routes go live, broadband can turn from a drag to a modest contributor, but the operating leverage is strongest only if customer acquisition costs stay controlled.

The contrarian view is that the stock’s drawdown may be premature if investors are extrapolating current roaming costs forward linearly. The build-out is now closer to an infrastructure completion story than a pure turnaround, and the implied payback should improve nonlinearly once coverage moves from ~30% toward mid-30s and external network payments start to roll off. The main tail risk is policy/spectrum failure: without better low-band access, coverage gains still happen, but traffic density and cost efficiency improve more slowly, extending the payback period and capping multiple expansion.

Key Decisions for Investors

• Go long 1&1 AG / short a European incumbent telco basket for 3-6 months: the long leg has operating leverage to self-network migration, while the short leg is exposed to slower growth and less margin expansion; best entry on any post-earnings weakness.
• Buy 1&1 AG on dips with a 6-12 month horizon only if the market price implies no second-half roaming relief; risk/reward improves once coverage milestones and partner launches are visible, with upside from margin normalization rather than top-line growth.
• Avoid chasing the move in full size until the next quarter confirms that pricing actions are not causing a larger-than-expected mobile subscriber slowdown; the near-term risk is a 1-2 quarter ARPU-vs-volume tradeoff.
• For more tactical exposure, consider a call spread in 1&1 AG into the next update: upside catalyst is evidence that self-network traffic and broadband net adds are improving, while downside is limited if the market continues to overfocus on current roaming costs.
• Relative-value idea: underweight Vodafone-linked wholesale exposure versus self-network builders over the next 6-12 months; any acceleration in 1&1’s own traffic should mechanically compress external capacity demand and pressure counterparties' roaming economics.
