Three companies, three outcomes

The largest self-storage REITs reported second-quarter results within three days of each other in late July 2026, and they did not describe the same market.

Extra Space Storage, reporting July 28, posted net income of $1.25 per diluted share, up 5.9% year over year, with core funds from operations of $2.15 per share, up 4.9%. Same-store revenue rose 2.4% while same-store expenses fell 0.5%, producing same-store net operating income growth of 3.5%. Ending same-store occupancy was 94.2%, against 94.4% a year earlier.

Public Storage, reporting July 29, recorded net income of $2.55 per share, up 44.9% from $1.76, while core FFO fell 2.6% to $4.17 per share. CubeSmart, reporting July 30, posted FFO as adjusted of $0.63 per diluted share, with same-store net operating income down 0.7% as revenue fell 0.8% and operating expenses rose 4.4%. Its same-store occupancy averaged 90.4% and ended the quarter at 91%.

Where the difference sits

The clearest contrast is on the cost line. Extra Space reported same-store operating expenses down half a percentage point; CubeSmart reported them up 4.4%. On revenue changes of well under one point in either direction, that expense gap alone is enough to flip net operating income from positive to negative.

A third-party synthesis by TractIQ published August 17 put sector-weighted same-store occupancy at 92.9% and the weighted average achieved rent at $21.19 per occupied square foot, 0.7% higher than a year earlier. By that analysis Extra Space and SmartStop posted positive same-store NOI growth of 3.5% and 3.7% respectively, while Public Storage at −2.2% and CubeSmart at −0.7% were negative.

Capital deployment continued regardless

Public Storage agreed during the quarter to acquire Public Storage Canada for US$1.2 billion, covering 68 properties and 5.3 million square feet, and separately acquired 20 US facilities totalling 1.5 million square feet for $222.5 million. It also put in place a new $3.0 billion unsecured revolving credit facility and a $500 million delayed-draw term loan.

Extra Space purchased 17 stores plus a joint venture buyout for $90.7 million in total and originated $140.6 million of bridge loans, while managing 2,373 third-party and joint-venture stores. CubeSmart's same-store pool covered 623 stores and 45.2 million square feet.

Analysis: companies reporting flat to negative same-store growth were nonetheless committing more than a billion dollars to acquisitions in the same quarter. That is consistent with owners treating current operating softness as cyclical rather than structural, though the filings state the transactions, not the reasoning behind them.

A comparison caution

Every figure above is affected by definitions that differ between the three companies. Each defines its own same-store pool — which properties qualify and for how long — so the pools are not the same set of assets, and core FFO and FFO-as-adjusted are non-GAAP measures constructed differently by each filer.

The TractIQ sector figures are a third-party synthesis rather than a primary aggregate, so sector-wide comparisons should be treated as indicative rather than audited.

What survives those caveats is that self-storage demand in mid-2026 was not strong enough to lift the whole group. Where owners grew, they grew by holding costs down rather than by raising rents.
