Three months ago SL Green delivered the most bullish quarter of its recent run, lifting full-year funds from operations guidance by roughly 26% and talking about Manhattan office demand with a confidence it had not shown in years. The stock has not cooperated. Shares are down about 5% since that report while the S&P 500 gained roughly 5%, leaving the landlord about 10 percentage points behind the market. When SL Green reports third-quarter results after the close on October 21, the job is to convince skeptics that the raise reflects durable leasing momentum and not mostly a change in how One Vanderbilt flows through the income statement.

The Street is looking for FFO of $1.51 per share, about 4.4% below the $1.58 earned a year ago but above the $1.43 posted last quarter. Revenue is expected at $175.6 million, a steep 28.3% drop from the prior year and well below the $264.0 million reported in the second quarter. Lumpy items such as asset sales, fee income and joint venture structures can swing the top line for a company actively recycling capital, so FFO matters more than the revenue figure. The more striking gap is on the annual outlook. Management now guides to $5.60 to $5.90 per share for 2026, up from $4.40 to $4.70, yet the full-year consensus still sits near $4.61, below the bottom of the new range. That suggests many estimates have not fully absorbed the raise, which makes this quarter the first real test of whether the higher run rate shows up in reported numbers.

The composition of that raise is the crux. Roughly $0.80 of the $1.20 increase comes from recurring One Vanderbilt negative-basis accounting, including about $21 million a year of amortization plus cash distributions above GAAP income. It is real FFO, but it is not fresh operating upside, and it can fluctuate with distributions. The remaining $0.40 is the part that speaks to the business: about $0.20 from early renewals, faster revenue recognition and expense control, and another $0.20 from fees and other income. A clean read on that operating slice, ideally tracking ahead of plan, would validate the narrative far more than the accounting tailwind.

Leasing metrics should provide that evidence. Economic occupancy jumped 300 basis points last quarter, and management expects to close at least half the gap to leased occupancy by year end while targeting 95% same-store leased occupancy. Another step up in economic occupancy, cash mark-to-market spreads holding near the 18% achieved last quarter, and further tightening in free rent would confirm that the leasing surge is converting into cash. Management even framed the question as whether it would beat leasing goals by a wide or a very wide margin, which sets a high bar. A stall in occupancy conversion or a retreat in spreads would undercut that swagger quickly.

Capital moves are the second test. The disposition plan was weighted to the second half, with 4 of 11 deals done or in contract, including 10 East 53rd at roughly a 5.7% cap rate. Progress on closings, the 245 Park financing amid wider benchmark rates, continued buybacks and any recapitalization path for Worldwide Plaza, 2 Herald and 650 Fifth will shape how much of the balance sheet story is real. Summit attendance, which slipped on soft tourism in the first half, should show the summer recovery management flagged.

Sentiment has warmed notably, at 43.6% bullish versus 24.5% before the last report, even as the stock trades closer to its post-earnings low of $47.01 than its $60.09 high, though still above its 200-day average. That disconnect frames the report. If SL Green shows the operating portion of its raise gaining traction and reaffirms the new range, the lagging estimates and the stock have room to catch up. If the quarter leans mainly on One Vanderbilt accounting, the market's doubts will look justified.
