What is GATX worth?
On an owner-earnings DCF, GATX's most-likely value is about $40 versus a recent price near $165 (76% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$24) with a margin of safety — so the honest verdict here is “Stretched — richly priced.” Fair value earns its keep only at the extremes, not in the wide middle.
Today's $165 is above even the optimistic Bull case ($54) — the market expects faster, longer growth than modeled here. Expensive unless that extra growth actually shows up.
⚠ High leverage — net debt is 159.5× 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.
⚠ Capital-intensive — this business reinvests heavily, so free cash flow runs well below its earnings. Fair value here is built on free cash flow, which understates owner earnings for reinvestment-heavy companies — read it as conservative.
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 →
