United Internet H1 Adj. EBITDA Rises; Confirms 2025 Guidance

United Internet reported a 2.0% increase in first-half adjusted EBITDA to €675.6 million, with sales rising 4.3% to €3.23 billion when adjusted for the pending divestiture of its "Energy" business field. Despite a slight decrease in operating earnings per share to €0.59, the company reaffirmed its full-year 2025 guidance, forecasting consolidated sales of approximately €6.45 billion and EBITDA of around €1.35 billion, both excluding the divested segment.

Analysis

United Internet's first-half 2025 results indicate a company in a stable but transitional phase, marked by a strategic divestiture. The firm posted a 2.0% year-over-year increase in adjusted EBITDA to €675.6 million, a key positive signal. Furthermore, core operational health appears solid, with sales growing 4.3% to €3.23 billion after adjusting for the pending sale of its "Energy" business field. This top-line growth in the continuing operations is a crucial indicator of future performance. However, this was contrasted by a minor decline in operating earnings per share to €0.59 from €0.61 in the prior year, suggesting potential margin pressure or increased costs below the EBITDA line. The most significant element for investors is the reaffirmation of full-year 2025 guidance, which projects approximately €6.45 billion in sales and €1.35 billion in EBITDA, excluding the divested unit. This confirmation provides a clear baseline for expectations and likely underpins the moderately positive market sentiment by reducing forward-looking uncertainty during a period of corporate restructuring.

Key Decisions for Investors

• Investors should focus on the 4.3% core sales growth as the primary indicator of the company's go-forward operational trajectory post-divestiture.
• The reaffirmed full-year guidance provides a solid anchor for valuation, but investors should monitor for any future revisions as a key catalyst for the stock.
• The slight decline in operating EPS warrants a closer look at profitability drivers below the EBITDA line, such as financing costs and tax effects, to understand the pressure on net earnings.
• Progress on the sale of the "Energy" business is a key event to watch, as the use of proceeds will be critical for the company's capital structure and future investment capacity.
