Is PSA a Buy? What to Consider in 2026
Short answer
The bull case for Public Storage (PSA) rests on Scale and Margin Leadership: Public Storage's roughly 78.4% same-store NOI margin is among the highest in the self-storage sector, supported by a low-cost digital leasing platform where over 85% of customers engage through self-help tools. Revenue (TTM) is ~$4.85 billion. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: The most immediate risk is that same-store revenue is already guided to decline in 2026 (PSA's own guidance calls for same-store NOI growth of negative 3.9% to negative 0.5%), reflecting ongoing supply pressure in Sunbelt and Southeast markets and soft post-pandemic consumer demand. Whether PSA is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Public Storage is a Maryland-based real estate investment trust (REIT) that acquires, develops, and operates self-storage facilities under the Public Storage brand. As of December 31, 2025, it owned or operated 3,533 self-storage facilities in 40 states encompassing roughly 258 million net rentable square feet, making it one of the two largest self-storage REITs in the United States by property count. The company derives revenue almost entirely from monthly rental income paid by individual and business customers renting climate-controlled and non-climate-controlled storage units. It also holds a 35% common equity interest in Shurgard Self Storage, which operates across seven European countries, providing modest international exposure. Additional income streams include tenant insurance programs, merchandise sales, and a growing third-party property management platform. In 2025, Public Storage acquired 87 facilities totaling 6.1 million square feet for $945.6 million, demonstrating active portfolio expansion alongside organic development. Public Storage was founded in 1972 by B. Wayne Hughes and Kenneth Volk Jr. and grew from a single facility in El Monte, California into the dominant national brand over five decades. The company has been listed on the NYSE as PSA and became an S&P 500 constituent as it scaled. Long-tenured CEO Joe Russell, who led a multi-year operational transformation, retired effective March 31, 2026. Under the PS4.0 initiative, Tom Boyle was elevated to CEO and Shankh Mitra became non-executive chairman effective April 1, 2026, signaling a new strategic phase focused on digital-first operations, margin expansion, and external growth through acquisitions, the first major move being the announced acquisition of National Storage Affiliates Trust.
What's the case for buying PSA?
Scale and Margin Leadership
Public Storage's roughly 78.4% same-store NOI margin is among the highest in the self-storage sector, supported by a low-cost digital leasing platform where over 85% of customers engage through self-help tools. Scale allows the company to spread fixed costs across a large asset base and negotiate more favorably on property taxes, insurance, and maintenance. From 2023 to 2025, management reported leading the sector in same-store revenue growth, NOI growth, and NOI margins, with total shareholder returns of approximately 18.6% outperforming peers over that period.
NSA Acquisition Adds Immediate Scale
The pending $10.5 billion all-stock acquisition of National Storage Affiliates, expected to close in the third quarter of 2026, would add over 1,000 properties across 37 states and Puerto Rico to PSA's portfolio. Management projects the deal to be accretive to FFO per share by $0.35 to $0.50 once annual cost synergies of $110 million to $130 million are fully realized within three to four years. Public Storage will wholly own 488 NSA properties and form a joint venture for the remaining 313, preserving balance-sheet flexibility while expanding brand and operational reach.
Supply Cycle Turning Favorable
New self-storage construction activity has been declining as higher interest rates and elevated construction costs deter new development, reducing the supply headwind that pressured rents through 2024 and 2025. PSA's Q3 2025 commentary noted that new competitive supply is declining, which management expects to support occupancy and pricing power. Strategically concentrated positions in land-constrained coastal markets like Los Angeles, New York, and Miami provide an additional structural barrier against new competition.
PS4.0 Digital and Operational Platform
The company's PS4.0 strategy pairs new leadership with a technology-driven operating model called PS Next, designed to optimize customer conversion, reduce staffing costs, and improve yield management across the portfolio. Over 85% of customers already engage through digital self-help tools, and the company is integrating AI to optimize lease conversion and cost per acquisition. Management believes this platform creates a durable cost and revenue advantage that can be layered onto newly acquired assets, including the NSA portfolio, to accelerate margin improvement.
What are the risks to PSA?
The most immediate risk is that same-store revenue is already guided to decline in 2026 (PSA's own guidance calls for same-store NOI growth of negative 3.9% to negative 0.5%), reflecting ongoing supply pressure in Sunbelt and Southeast markets and soft post-pandemic consumer demand. Absorbing more than 1,000 NSA properties through an all-stock deal introduces integration complexity and shareholder dilution, and any delay or regulatory complication in closing the transaction could weigh on the stock. A prolonged high-rate environment increases borrowing costs on PSA's $10.3 billion debt load and compresses REIT valuations broadly, while the GAAP dividend payout ratio above 120% raises the question of how long the current $12.00 annual dividend is sustainable if FFO growth stalls. Regulatory pressure on rents in states like California and rising property tax and insurance costs add further margin headwinds.
How is PSA valued? (as of 2026-06-27)
- Revenue (TTM): ~$4.85 billion
- Full-Year 2025 Revenue: ~$4.82 billion
- Net Income (FY 2025): ~$1.78 billion
- Core FFO per Share (FY 2025): ~$16.97
- Trailing P/E Ratio: ~32x (trailing); ~29x (forward)
- Annual Dividend per Share: $12.00 (~4.5% yield)
- Same-Store NOI Margin (Q4 2025): 78.4%
- Total Debt: ~$10.3 billion
PSA trades at a trailing P/E of roughly 32x, above its own 3-year average of approximately 25x to 27x and above the broader real estate sector average, reflecting the market's expectation that the NSA acquisition and the PS4.0 platform will reaccelerate growth. For REITs, Core FFO per share is the most widely watched profitability metric; PSA's 2025 Core FFO of $16.97 reached the high end of guidance and grew 1.8% year over year, while 2026 guidance of $16.35 to $17.00 implies flat to modestly positive growth. The GAAP payout ratio exceeds 100% of net income, which is normal for REITs given depreciation charges, but the ratio relative to Core FFO is the more relevant measure of dividend coverage.
How do you decide if PSA is a buy?
Rather than asking whether PSA is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold PSA indirectly through an index or sector ETF before adding more.

What does Public Storage do?
+
Public Storage is a real estate investment trust (REIT) that owns and operates self-storage facilities, renting climate-controlled and standard storage units to individuals and businesses on monthly leases. As of December 31, 2025, it operated 3,533 facilities across 40 U.S. states with roughly 258 million net rentable square feet, making it one of the two largest self-storage companies in the country.
Is PSA a good stock to invest in right now?
+
That depends on your investment horizon and risk tolerance. PSA offers a roughly 4.5% dividend yield, industry-leading NOI margins, and potential upside from the NSA acquisition and PS4.0 platform. Against that, same-store revenue is guided to decline in 2026, the all-stock NSA deal introduces dilution risk, and the stock trades above its own historical average earnings multiple. Whether that setup is attractive depends on your view of the supply cycle and integration execution.
Does PSA pay a dividend?
+
Yes. Public Storage pays a quarterly dividend of $3.00 per share, totaling $12.00 per share annually, which equates to approximately a 4.5% yield at recent prices. The dividend has grown at an average rate of roughly 15% over the past three years. However, PSA's GAAP payout ratio is currently above 100% of net income, which is common for REITs due to large depreciation charges; Core FFO coverage is the more relevant sustainability measure.
Who are Public Storage's main competitors?
+
PSA's primary competitors are other large self-storage REITs: Extra Space Storage (EXR), which surpassed PSA in property count after acquiring Life Storage, and CubeSmart, the third-ranked public self-storage REIT. National Storage Affiliates (NSA), previously the fourth-ranked REIT, is now the subject of a pending PSA acquisition. Beyond REITs, PSA competes with thousands of private and local operators who collectively control the majority of U.S. self-storage space.
