1&1 AG stock (ISIN DE0005545503) is trading slightly weaker after the company approved a restructuring program at its 1&1 Versatel unit and lowered its 2026 EBITDA guidance to about EUR 740 million on September 10, 2026. According to Finanzen.ch on September 10, 2026, the program triggers one-off expenses of around EUR 60 million in 2026 but is expected to lift annual earnings by about EUR 25 million from fiscal year 2028.

Restructuring weighs on 2026 earnings

As Finanzen.ch reports, 1&1 now expects EBITDA of approximately EUR 740 million in fiscal year 2026 instead of an earlier higher forecast, while adjusted EBITDA is still projected at around EUR 800 million for the same period. The change is driven by one-time restructuring expenses of about EUR 60 million in 2026, which will reduce reported earnings in the short term but are intended to streamline the network and business structure.

According to the same report from Finanzen.ch, the broader United Internet group anticipates one-off restructuring expenses of around EUR 95 million in fiscal year 2026, but still backs its operating EBITDA guidance of about EUR 1.45 billion. For investors in 1&1 stock this means that the subsidiary carries roughly two-thirds of the group’s restructuring burden, yet its underlying adjusted earnings profile remains intact.

Analyst and market reaction around the SDAX listing

The restructuring announcement came via an ad hoc release dated September 10, 2026, in which the board of 1&1 AG decided on the transformation and restructuring program at 1&1 Versatel and confirmed the company’s SDAX index membership. According to FinanzNachrichten, the company highlighted that the measures are designed to improve efficiency in its fiber and carrier business.

Market portals show that 1&1 shares reacted only moderately to the updated guidance. Per price data from a German stock portal, the stock traded around EUR 24.00 on Xetra at the close on September 10, 2026, after moving intraday between about EUR 23.95 and EUR 24.05, and ended the session with a loss of around 1.7 percent versus the previous close. That put 1&1 stock somewhat below recent SDAX levels where the share had stood at EUR 23.05 on August 28, 2026, with a flat daily move.

Stock price and trading data

On September 11, 2026, intraday data from Xetra show 1&1 stock changing hands at EUR 24.05, up 0.21% from a prior reference level of EUR 24.00, with volume of 11,594 shares as of 11:28. The shares thus trade slightly above the EUR 23.55 close reported for September 10, 2026, and remain within a narrow range around EUR 24 in the aftermath of the guidance cut.
