What Is Sunrise Communications' Investment Narrative?

To believe in Sunrise Communications as a shareholder right now, you’d need to have confidence in its ability to turn the corner on profitability while managing sluggish revenue growth. The new inclusion in the S&P Global BMI Index could serve as a short-term catalyst, potentially drawing more passive inflows and profile for the stock at a point when its fundamentals are in a rebuilding phase after last year’s spin-off from Liberty Global. That said, the underlying business is still posting losses despite modest improvements and a stable dividend policy. Prior to this index change, the main risks were margin pressure, slow top-line growth, and whether the turnaround on profits would stick. With visibility from index inclusion, some risk shifts to whether the broader investor interest translates into real, sustained buying, or simply heightened expectations without material fundamental change. The catalyst is real, but the heavy lifting comes down to delivering core operational progress.

But investors need to be mindful of margin pressure that may not be fully offset by index flows. Sunrise Communications' shares have been on the rise but are still potentially undervalued by 23%. Find out what it's worth.
