What Harmonic does
Harmonic Inc., founded in 1988 and headquartered in San Jose, California, provides broadband access solutions to cable and telecom operators worldwide.

It is paired with hardware including Oyster, Ripple and SeaStar distributed access nodes, Reef and Wave PHY shelves, Pebble remote PHY devices, and Fin, Pearl and Pier OLT fiber modules. Besides software and equipment, Harmonic sells cOS Central, a subscription cloud service for cOS customers, and offers a wide range of services: maintenance and support, consulting, system integration, network design, site preparation, installation, end-to-end testing and training.

What is Harmonic worth?
On an owner-earnings DCF, Harmonic's most-likely value is about $14 versus a recent price near $11 (32% below fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$7) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
