What is Resideo Technologies worth?
On an owner-earnings DCF, Resideo Technologies's most-likely value is about $39 versus a recent price near $17 (129% below fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$22) with a margin of safety — so the honest verdict here is “Deeply discounted.” Fair value earns its keep only at the extremes, not in the wide middle.
On the financials alone, $17 is below even the no-growth floor ($22); the market's discount — expectations and sentiment beyond the numbers — is pricing in ≈ -3.8%/yr. A bargain only if that pessimism is overdone.
⚠ High leverage — net debt is 8.7× annual cash flow. Net debt is subtracted from this fair value, but refinancing at higher rates, principal timing, and share dilution aren’t modeled — the equity can be worth far less if cash flow weakens.
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 →
