SLG vs VNO: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. SLG and VNO share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined SLG and VNO exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

SL Green Realty Corp. is a fully integrated real estate investment trust (REIT) and Manhattan's largest office landlord, focused on acquiring, managing, and maximizing the value of New York City commercial properties. As of March 2026 the company held interests in roughly 55 buildings totaling about 30.8 million square feet, anchored by trophy assets such as One Vanderbilt (home of the SUMMIT observation deck) and One Madison Avenue. Beyond straight ownership, SLG runs an active debt-and-preferred-equity investment book and periodically recycles capital through asset sales and joint ventures.

Vornado is a fully integrated real estate investment trust organized in Maryland and run from 888 Seventh Avenue in New York. It reports in two segments, New York and Other. The New York segment covers all or portions of 51 Manhattan operating properties: roughly 19.2 million square feet of office space across 26 buildings, about 2.3 million square feet of street retail across 45 buildings, 1,331 apartments, the signage business in the PENN District and Times Square, and a 32.4% interest in Alexander's (NYSE: ALX), owner of the Bloomberg headquarters at 731 Lexington Avenue. The Other segment holds THE MART in Chicago (~3.7 million square feet) and that 70% interest in the ~1.8 million square foot 555 California Street complex. A wholly owned subsidiary called Building Maintenance Services cleans and secures the buildings, which is why headcount looks large for a landlord: ~3,145 employees as of December 31, 2025, of whom ~2,725 sat at BMS.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• SLG drivers: Manhattan office recovery and leasing momentum; Trophy assets and SUMMIT.
• VNO drivers: The 350 Park Avenue decision; PENN District rent commencements.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: SLG is highly concentrated in Manhattan office real estate, so a downturn in New York City office demand, tenant defaults, or a shift toward remote work would hit it directly with little diversification to cushion the blow. For VNO, the ~$244.5 million non-recourse mortgage on 888 Seventh Avenue matured in December 2025 without being repaid, the lenders declared an event of default, and a March 2026 forbearance defers the reckoning only to March 2027.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick SLG if you believe its drivers more; VNO if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the SLG and VNO guides.

SLG. SLG reported Q1 2026 FFO of about $0.84 per share and reaffirmed full-year FFO guidance of roughly $4.40 to $4.70 per share, even as it booked a GAAP net loss of about $1.20 per share. REITs are generally valued on FFO and net asset value rather than earnings per share, so the net loss reflects heavy depreciation more than cash-flow weakness. The high dividend yield and elevated leverage are the two figures that most define how the market prices the stock.

VNO. Vornado is judged on FFO rather than net income, because depreciation on a Manhattan portfolio swamps GAAP earnings. The company reported a small net loss attributable to common shareholders for the first half of 2026 while adjusted FFO was ~$1.19 per diluted share, flat against 2025. At ~$39.94 the shares trade near ~17 times annualized first-half adjusted FFO and yield ~1.9%, so the swing factors are occupancy, renewal rent spreads and interest expense.

Headline figures (approximate, July 2026): SLG shows revenue (ttm) ~$1.0B, q1 2026 revenue ~$253M, q1 2026 ffo ~$0.84/share, 2026 ffo guidance ~$4.40 to $4.70/share; VNO shows revenue (ttm through june 2026) ~$1.83B, ffo as adjusted (q2 2026) ~$0.67 per diluted share, vs ~$0.56 a year earlier, occupancy at share (june 30, 2026) ~87.5% total, ~90.8% New York office, consolidated debt (june 30, 2026) ~$7.5B, weighted average rate ~4% to ~5%.

SLG and VNO are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined SLG and VNO exposure against your real portfolio. It is not an investment adviser.
