Harmonic Investment Narrative Recap

To own Harmonic, you need to believe in its role as an enabler of next generation broadband, particularly virtualized and fiber-grade access. The DNA Finland SeaStar deployment reinforces this thesis by highlighting Harmonic’s ability to extend multi-gigabit connectivity using existing coax, but it does not materially change the near term reliance on a concentrated customer base or the risk that technology shifts could erode its product relevance.
