How ABM Industries makes money

It also earns project and maintenance revenue from mechanical, electrical, EV charging and microgrid installations.
What ABM Industries does
ABM Industries, founded in 1909 and headquartered in New York, is one of the long-established providers of outsourced facility services in the United States, with some international operations. It reports five segments: Business & Industry, Manufacturing & Distribution, Education, Aviation, and Technical Solutions. Its core work is janitorial, facilities engineering and parking for commercial offices, sports venues, hospitals and healthcare sites. It also serves factories, distribution centers and data centers, and provides custodial and grounds work for schools and universities. In Aviation, ABM supports airlines and airports with passenger assistance, catering logistics, cabin maintenance and transportation. It also provides vehicle maintenance for rental car companies. The Technical Solutions segment covers mechanical and electrical infrastructure, including EV charging and microgrid design, installation and maintenance. This gives ABM exposure to electrification alongside its recurring, labor-based service contracts.

What is ABM Industries worth?
On an owner-earnings DCF, ABM Industries's most-likely value is about $76 versus a recent price near $50 (54% below fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$48) 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.
⚠ High leverage — net debt is 5.5× 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.
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 →
