Price around EUR 23 on German venues

According to the Xetra and regional-exchange overview compiled by OnVista, 1&1 shares recently traded at EUR 23.35 on the Stuttgart exchange, reflecting a small decline of EUR 0.10 or 0.43% compared with the previous reference price as of intraday trading on September 3, 2026.

United Internet half-year 2026 figures underpin the valuation

As 1&1 is part of the United Internet group, investors closely watch the parent company’s latest financial results as an anchor for valuation. A recent analysis of United Internet’s shares on ad-hoc-news.de notes that the parent company reported its half-year 2026 figures for the six months ended June 30, 2026, with group revenue and EBITDA continuing to grow compared with the prior year period, based on company data and financial-portal summaries, even if the detailed euro values are described only qualitatively in that overview. The same report highlights that United Internet’s half-year 2026 revenue reached a mid single-digit billion-euro level, modestly above the prior-year half, while EBITDA increased at a high single-digit percentage rate, signaling improved profitability trends on a group level.

For context, the ad-hoc-news.de snapshot states that United Internet stock closed at EUR 27.24 on Xetra as of September 2, 2026 after trading between EUR 26.80 and EUR 27.24 during that session, keeping the parent company’s shares near the upper end of their intraday range and suggesting a relatively firm TecDAX backdrop for 1&1 as well. The combination of mid single-digit percent revenue growth and high single-digit percent EBITDA growth in H1 2026 for United Internet provides a supportive fundamental framework for 1&1’s current price region around EUR 23.

Tele Columbus agreement highlights network strategy

Beyond the group’s headline figures, operational developments in broadband infrastructure also play a role for 1&1’s medium-term outlook. In a recent earnings call transcript summarized by Investing.com, Tele Columbus reported that it closed an agreement with 1&1 in May 2026 that is currently being implemented.

Tele Columbus itself reported Q2 2026 revenue of EUR 209 million, down 0.9% year over year, while normalized EBITDA increased nearly 2% in the quarter and internet and telephony revenue rose 5.4% to EUR 60 million, illustrating how fiber and high-speed access remain growth areas even as legacy TV business declines. For 1&1, the cooperation with Tele Columbus supports its strategy of expanding high-speed fixed-line access across Germany, complementing its mobile network rollout and helping the company broaden bundled offerings to consumer and business customers.

Representative product focus: 1&1 mobile and broadband tariffs

1&1 generates a significant portion of its revenue from mobile and fixed broadband tariffs for private and corporate customers in Germany. Typical offerings include LTE and 5G mobile contracts with data volumes ranging from entry-level to high-volume packages, as well as VDSL and fiber-based broadband tariffs for households and small businesses. These products are usually sold in combination with additional services such as hosting, cloud applications or entertainment bundles, which helps the company increase average revenue per user over time.

Stock level and investor perspective

Based on the latest consolidated quotation overview from OnVista as of intraday trading on September 3, 2026, 1&1 stock can be considered to be trading around EUR 23.35 on German regional exchanges, with a Tradegate indication of EUR 23.40, reflecting only minor intraday changes and placing the shares in the mid-20-euro corridor in the current TecDAX setting.
