If your same-store NOI grew less than 4.6% in Q3, you trailed Extra Space. Less than 2.1%, and you trailed CubeSmart too.
On a 50,000 NRSF store, that 2.5-point spread is $12,456 a year. A bit more than half of it comes from the expense line, not from rates.
So before you set 2027 budgets, find out which line moved your NOI. The numbers are below, then the split to run on your own P&L.
The numbers
All three big public operators reported positive same-store revenue and NOI growth. The table covers Extra Space and CubeSmart, the two with full same-store figures in the recap.
| Q3 2026 vs Q3 2025 | Extra Space | CubeSmart | Source |
|---|---|---|---|
| Same-store revenue | +2.7% | +1.9% | MSM |
| Same-store expenses | -1.8% | +1.3% | MSM |
| Same-store NOI | +4.6% | +2.1% | MSM |
| Occupancy at Sept. 30 | 94.0% | 89.9% | MSM |
| Shares bought back | $327.1 million | $83.9 million | MSM |
| Stores managed for third parties | 1,963 | 882 | MSM |
CubeSmart's same-store pool is 623 stores. Extra Space's pool isn't given and the two differ, so compare direction, not exact levels.
Public Storage raised its full-year 2026 outlook, lifting Same Store NOI guidance by 90 bps and Core FFO per share guidance by $0.10. The recap doesn't give the old range.
What's behind them
Revenue growth was modest at both. Public Storage's CEO pointed to churn, occupancy and move-in rates as the drivers on its side:
"We continue to post encouraging trends on churn, occupancy, and move-in rates, which drove positive Same Store revenue, NOI and Core FFO per share growth." Tom Boyle, CEO, Public Storage, via Modern Storage Media
Expenses made the difference. Extra Space's costs fell 1.8% and CubeSmart's rose 1.3%, per the same recap. The recap doesn't say what drove Extra Space's drop, so don't assume it was payroll or marketing.
Occupancy moved in different directions. Extra Space ended September at 94.0%, up from 93.7% a year earlier. CubeSmart averaged 90.5% over the quarter and ended at 89.9%, so it was fuller earlier in the quarter than at the finish.
Capital is still moving. Public Storage finished buying National Storage Affiliates and Public Storage Canada, which put more than 1,100 stores on its PS Next platform. Outside those two deals, it bought 25 facilities with 1.7 million NRSF for $258.4 million, per the recap. That works out to about $152 an NRSF, using the rounded square footage.
Extra Space and CubeSmart both spent heavily on their own stock. Both also run large third-party management platforms, which matters if a REIT-run store sits near yours. Our post on switching third-party managers covers what you keep and what you hand over.
What it means for your facility
The headline NOI number hides which line moved. Split it, and you can see whether your growth came from the rent roll or from cost control.
Assume a 50,000 NRSF facility earning $1.20 a foot a month, which is $720,000 a year in revenue. Assume expenses run 30% of revenue, or $216,000, which leaves $504,000 of NOI. Swap in your own figures.
Apply each company's Q3 pattern to that base:
| Pattern | Revenue | Expenses | NOI | Change |
|---|---|---|---|---|
| Your base year | $720,000 | $216,000 | $504,000 | |
| Extra Space pattern | $739,440 | $212,112 | $527,328 | +$23,328 |
| CubeSmart pattern | $733,680 | $218,808 | $514,872 | +$10,872 |
The Extra Space pattern adds $12,456 more NOI than the CubeSmart pattern. Of that, $5,760 is the faster revenue growth and $6,696 is the expense line moving the other way.
So the cheapest NOI in your building may not be a rate increase. Extra Space's 1.8% expense cut on a $216,000 expense base is worth about $3,888, and it doesn't depend on a single extra move-in.
Occupancy is the other lever, and it's worth pricing too. On the same facility, one point of occupancy is 500 NRSF. At $1.20 a foot, that's $600 a month, or $7,200 a year. CubeSmart's ending occupancy sat 4.1 points under Extra Space's, and 0.6 points under its own quarterly average.
Our read as operators: at these two companies, the gap came more from costs and occupancy than from revenue. Our posts on rate cuts and move-ins and on physical versus economic occupancy show why a rate move alone rarely fixes a weak quarter.
What to check this week
- Pull Q3 2026 and Q3 2025 revenue, expenses and NOI for the same set of stores. Leave out any store still in lease-up.
- Split the NOI change into the revenue part and the expense part, the way the table above does. Know which one is carrying you.
- Compare occupancy at Sept. 30 to your Q3 average. If you ended below it, look at your vacates by week.
- Go through each expense line against last year and flag any that rose faster than revenue.
- If a Public Storage or CubeSmart store is in your trade area, check your street rates, your GBP and your Map Pack position against theirs.
