A cash-flow DCF is not the right model for SLG
SL Green Realty Corp. is a bank, insurer, or real estate company. A standard discounted cash flow model values a business on its free cash flow, but for these companies free cash flow is not a clean measure of value. Banks and insurers are valued on book value, return on equity, and a price-to-earnings multiple; REITs are valued on funds from operations (FFO) and dividends, not free cash flow. Running a free cash flow DCF here would produce a misleading number, so none is shown.

COMPETITIVE MOAT
↑Prime Manhattan Portfolio
SL Green owns a significant portfolio of high-quality office buildings in prime Manhattan locations. This concentration in a globally recognized business hub provides a durable advantage.
↑Tenant Relationships and Lease Stability
Long-term leases with established tenants create predictable revenue streams. Strong relationships can lead to renewals and reduced vacancy risk in their prime assets.
↑Scale and Market Expertise
As a large owner of Manhattan office space, SL Green possesses deep market knowledge and operational expertise. This scale allows for efficient management and strategic acquisitions/dispositions.
INVESTMENT RISKS
↓Economic Downturn Impact
A significant economic recession could lead to tenant defaults and increased vacancy rates. This would negatively affect rental income and property valuations.
↓Lease Expirations and Re-leasing
The expiration of large leases presents a risk if market conditions are unfavorable for re-leasing at current or higher rates. This could lead to periods of reduced income.
↓Capital Market Access
Deteriorating capital markets or a weakening balance sheet could limit SL Green's ability to refinance debt or fund new investments. This could hinder growth and operational flexibility.

Frequently Asked Questions
Why isn't a discounted cash flow model right for valuing SL Green Realty Corp.?
As a REIT, SL Green Realty Corp. must pay out most of its income as dividends and carries heavy non-cash depreciation on its buildings, so reported net income and free cash flow understate how much the properties actually earn. A DCF built on those figures misses the real cash the portfolio produces. A REIT is read on funds from operations and dividends instead.
How is SL Green Realty Corp. (SLG) valued instead?
SL Green Realty Corp. is better read through price-to-FFO, which uses funds from operations, and the dividend yield rather than price-to-earnings, together with occupancy and the quality of its properties. The SLG PE view is a starting point, but multiples based on funds from operations fit a REIT better.
