Key Highlights

• Extra Space grew same-store Revenue 2.4% while Public Storage's slipped 0.6%, even as Public Storage posted its first positive move-in rent growth since 2021.

• Public Storage closed its all-stock Merger with National Storage Affiliates on July 22, 2026, expanding to more than 4,500 locations.

• Both REITs are above 92% occupancy, so pricing rather than filling vacant units now drives revenue growth for each.

Rent per square foot, not occupancy, now separates the results at Public Storage (NYSE:PSA) and Extra Space Storage Inc. (NYSE:EXR), a shift in storage pricing worth close attention. Both S&P 500 self-storage real estate Investment trusts are close to full, so revenue growth depends on what they can charge new and existing customers. In the second quarter of 2026, Extra Space grew same-store revenue while Public Storage's slipped, even though Public Storage reported its first rise in move-in rents since 2021.

Why Price Is the Main Lever

A self-storage operator's revenue is roughly occupied space multiplied by the rent achieved. With both companies above 92% occupancy, there is limited room to grow by filling units, so pricing matters more.

Pricing works on two fronts. Move-in or street rates, often supported by discounts and advertising, determine how many new customers arrive and at what starting rent. Existing customer rate increases then lift rents for tenants already in place, which is where much of the sector's profit is made. When move-in rents fall, operators must choose between lower occupancy and a lower-rent customer base.

Because storage costs, such as property tax, Payroll and utilities, are relatively fixed, small changes in rent flow strongly into net operating income, the property-level profit before interest, Depreciation and corporate costs.

Public Storage (NYSE:PSA): Better Occupancy, Rents Still Lagging

For the three months to June 30, 2026, reported on July 29, 2026, Public Storage's 2,755 same-store facilities generated revenue of $1.01 billion, down 0.6%. Realised annual rent per occupied square foot fell 0.8% to $21.89, while average occupancy edged up to 92.5% from 92.3%.

Direct operating costs rose 4.3%, so same-store net Operating Income declined 2.2%. Core funds from operations, a REIT Earnings measure that excludes property depreciation and certain one-off items, fell 2.6% to $4.17 per share, although reported Net Income per diluted share rose to $2.55 from $1.76.

The pricing signal is improving. Average move-in rents rose 1.6% year on year, the first positive reading since 2021, after falling 2.4% in the first quarter. Management also cited a 50 basis-point drag on 2026 same-store revenue growth as Los Angeles County state-of-emergency pricing restrictions unwind gradually.

Public Storage raised 2026 guidance: core FFO of $16.75 to $17.05 per share and same-store revenue of minus 0.7% to plus 0.3%, up from minus 2.2% to zero. Even the top of that range implies little growth from the mature portfolio this year.

Outside the same-store pool, total revenue rose to $1.23 billion from $1.20 billion, helped by acquisitions of 44 facilities for $454.9 million in the first half and newly developed space. Its development and expansion pipeline totals about 4.0 million square feet at a cost of roughly $692 million, so the company is itself adding capacity that must be let at viable rents.

Extra Space (NYSE:EXR): Supply Relief Helps Pricing

Extra Space, reporting on July 28, 2026, grew same-store revenue by 2.4% to $690.2 million across 1,870 wholly-owned stores, while same-store expenses fell 0.5%. That produced same-store net operating income growth of 3.5% and a 4.9% rise in core FFO to $2.15 per share.

Occupancy dipped to 94.2% at June 30 from 94.4%, which implies higher achieved rents rather than extra Volume drove the gain. Chief executive Joe Margolis described Demand as steady, saying the company had not seen any pickup in the housing market, and credited reduced new supply instead. Extra Space raised 2026 same-store revenue guidance to 1% to 2% and core FFO to $8.25 to $8.40 per share, while cutting its same-store expense growth forecast to 1% to 2% from 2% to 3.5%.

Margolis's month-by-month description underlines how finely balanced pricing remains. The company was slightly ahead on rate but behind on occupancy year on year in June, and the reverse in July. Management said lower supply could eventually support a return to historical revenue growth of 3% to 4%, which is an aspiration rather than guidance.

Scale Changes the Comparison

Public Storage (PSA) completed its all-stock merger with National Storage Affiliates on July 22, 2026, taking it to more than 4,500 locations and 327 million square feet, and agreed on June 22 to buy PS Canada for $1.2 billion, expected to close in the third quarter. Pricing across roughly 1,100 acquired stores will therefore shape future results, and core FFO per share will reflect the new share count.

Extra Space (EXR), which operated 4,410 stores at June 30, leans more on capital-light income. It managed 1,964 stores for third-party owners and had about $1.5 billion of bridge loans outstanding to storage owners. Those fees and interest cushion earnings when rents soften, but also tie the company to its partners' health. In the second quarter it also bought 17 operating stores and a joint-venture interest for $90.7 million, a far smaller outlay than Public Storage's deal activity.

What Could Undermine the Pricing Story

One quarter of positive move-in rents does not confirm a trend; Public Storage's rate turned positive only after a weak first quarter. Heavier discounting or Advertising to protect occupancy would erode the benefit. Regulatory scrutiny of rate increases for existing tenants remains a risk, as the Los Angeles restrictions show.

Demand also remains subdued. Housing transactions, a traditional driver of storage demand, have not recovered, according to Extra Space's chief executive. If new development picks up again, the supply relief behind Extra Space's growth could fade. Integration of National Storage Affiliates adds execution risk at Public Storage. Higher interest rates would also raise the cost of funding acquisitions and development for both groups.

Pricing-Power Signals Ahead

Watch whether Public Storage's move-in rent growth persists alongside stable occupancy, and how realised rent per occupied square foot trends. For Extra Space, the balance between occupancy and rate that management described month by month is key. Both companies' revised 2026 same-store guidance, Public Storage's National Storage Affiliates integration and the PS Canada closing will show whether pricing power is genuinely returning.
