How to Compare Banks, REITs and Operating Companies

The short answer

A universal ratio template creates category errors. Interest is operating revenue and expense for a bank; customer deposits are core funding, not ordinary corporate debt. Real-estate depreciation can depress REIT net income even when property cash economics are stable. An industrial or software company usually needs an earnings-to-operating-cash bridge and capital-expenditure estimate. Compare within each model first, then use a common shareholder lens such as per-share value growth, payout durability, and downside resilience.

1. Match each business to its economic engine

2. Bank example: earnings require credit and capital context

JPMorgan Chase's 2024 Form 10-K reports $177,556 million of total net revenue, $10,678 million of provision for credit losses, and $58,471 million of net income. The 22% reported return on tangible common equity and 15.7% standardized CET1 capital ratio add return and solvency context that an operating-company FCF margin would miss.

Reported results also included a $7.9 billion gain related to Visa shares and a $1.0 billion contribution of Visa shares to the firm's foundation. A comparison must retain GAAP net income and show the company's reconciliation before discussing an adjusted return. Then examine net interest income, net charge-offs, allowance coverage, loan mix, deposit costs, risk-weighted assets, stress losses, and tangible book value per share.

The provision is a forward-looking estimate of credit losses, while charge-offs reflect losses recognized against the allowance. Comparing banks on earnings without underwriting their credit assumptions can reward the least conservative estimate at the wrong point in the cycle.

3. REIT example: reconcile net income to property cash measures

Realty Income reported 2024 net income available to common stockholders of $847.9 million. Its filed FFO reconciliation adds real-estate depreciation and amortization and impairment provisions, removes gains on property sales and other specified items, producing $3,467.7 million of FFO available to common stockholders. Diluted FFO per share was $4.01.

The company reported $3,621.4 million of AFFO available to common stockholders and diluted AFFO per share of $4.19. Distributions of $3.126 per share were 74.6% of diluted AFFO per share. The reconciliation is essential because AFFO is non-GAAP and issuers can define adjustments differently.

Aggregate FFO grew 22.9%, but FFO per share fell 1.5%. Realty Income completed a stock-for-stock merger with Spirit Realty during 2024, so the per-share outcome prevents scale growth from being mistaken for owner growth. Also review 98.7% occupancy, lease expirations, tenant concentration, acquisition yields, property dispositions, debt maturities, secured versus unsecured funding, and recurring capital expenditure.

4. Operating-company example: connect margin to reinvestment

Alphabet's 2024 filing reports $350,018 million of revenue, $112,390 million of operating income, $125,299 million of operating cash flow, and $52,535 million of property/equipment purchases. That produces a 32.1% operating margin and $72,764 million of simple FCF.

Those measures suit an operating-company workflow, but still need segment mix, working capital, stock-based compensation, acquisitions, leases, and maintenance-versus-growth capex. Applying Realty Income's FFO formula would remove depreciation without the real-estate-specific rationale; applying a bank's CET1 ratio would have no equivalent regulatory meaning.

5. Build comparisons in two stages

1. Within-model: compare each company with genuine peers using model-specific definitions.
2. Across-model: compare per-share growth, payout, balance-sheet resilience, valuation assumptions, and downside loss.
3. Label regulatory, GAAP, industry-standard, company-defined, and analyst-defined measures separately.
4. Reconcile every non-GAAP measure to the closest GAAP amount.
5. Use the same price date and aligned fiscal or trailing periods.
