Public Storage announced this morning that it will acquire National Storage Affiliates (NSA) in an all-stock transaction valued at approximately $10.5 billion, further cementing its position as the largest player in the self-storage REIT sector. MSM was on the call and has the details, along with a condensed Q&A from company leadership.
The deal will add more than 1,000 properties totaling roughly 69 million rentable square feet and about 550,000 units across 37 states and Puerto Rico to Public Storage’s portfolio. Following the acquisition, the combined company is expected to have a pro forma equity market capitalization of about $57 billion and an enterprise value of roughly $77 billion.
Under the terms of the agreement, NSA shareholders and operating partnership unitholders will receive 0.14 shares of Public Storage stock for each NSA share, representing an implied value of $41.68 per share based on PSA’s March 13 closing price. The transaction has been unanimously approved by both companies’ boards and is expected to close in the third quarter of 2026, pending NSA shareholder approval and customary closing conditions.
As part of the transaction structure, Public Storage and certain NSA operating partnership unitholders will form a joint venture comprising 313 properties valued at approximately $3.3 billion. The venture will include 19.6 million rentable square feet across 28 states and Puerto Rico, with NSA unitholders expected to hold roughly 80 percent ownership at inception while Public Storage retains the remaining stake and management responsibilities.
Public Storage expects to wholly own 488 properties from NSA’s portfolio, focusing particularly on assets in Sun Belt and other high-growth markets. The company said the acquisition will deepen its presence in regions benefiting from favorable demographic trends and population growth.
The transaction also marks a key early move under Public Storage’s new PS4.0 strategic plan, which incoming CEO Tom Boyle has positioned as a framework for accelerating earnings growth and expanding the company’s operating platform.
“With the launch of the PS4.0 strategic vision focused on accelerated per-share earnings and cash flow growth, this transaction will enable us to strategically and accretively expand our platform with assets that are highly complementary to our portfolio,” Boyle said during the investor call.
Public Storage expects the deal to be accretive to funds from operations within the first year following closing, with an estimated $110 million to $130 million in annual run-rate synergies achievable within three to four years through revenue enhancements, operational efficiencies and cost savings.
NSA CEO David Cramer said the transaction represents the culmination of several years of portfolio repositioning and operational improvements.
“This outcome reflects the incredible transformation we have undertaken over the past few years to refocus our portfolio, enhance operations and drive growth,” Cramer said. “Public Storage is the ideal strategic fit for our company given its best-in-class brand and operating platform.”
Public Storage said the combined company will benefit from its industry-leading operating margins and A/A2 credit rating, allowing it to leverage a lower cost of capital to fund future acquisitions, development and expansion opportunities.
Questions and answers have been edited for length and clarity.
Q: Can you provide more detail on the $60 million to $65 million of revenue synergies, including timing and how much comes from occupancy upside versus price optimization?
A (Joe Russell): We expect to realize all synergies by the end of year three. On the revenue side, the gains are expected to come from both occupancy improvement and rate increases. Occupancy is projected to rise from the mid-80% range to roughly 90%, while pricing will be adjusted over the next several years. Altogether, we expect total revenue growth of about 11% to 15%, helped by stronger brand presence, better revenue management, improved marketing, broader customer acquisition and better retention driven by customer experience.
On the expense side, the $10 million to $15 million of expense synergies should take about two years to fully realize, with most of the benefit coming from payroll efficiencies, plus some gains in marketing, insurance and utilities. The tenant reinsurance synergies are expected to take about three years, while around 75% of the G&A synergies should be realized in year one and 100% by year two.
Q: Are you planning to rebrand the entire NSA portfolio to Public Storage, including the existing and new joint ventures? And what is the timing of that spend and rebranding process?
A (Tom Boyle): Yes, we envision rebranding the assets to the Public Storage brand. We have spent the last five years refreshing and rebranding our own portfolio, and we see meaningful customer benefit from doing so here as well.
Q: How soon after closing do you plan to integrate the assets onto Public Storage’s pricing and revenue-management systems?
A (Tom Boyle): Integration will happen effectively immediately. We have discussed our integration capabilities before and pointed to prior case studies showing we can move assets onto our systems quickly. We expect to be highly focused on integration in the months after closing.
Q: Given the moving pieces of the joint ventures and OP units, how are you thinking about the cap rate for this transaction?
A (Tom Boyle): The portfolio is being valued at a loaded mid-5% cap rate on a going-in basis, with a price of around $180 per square foot. The bigger story is the value-creation opportunity from moving the assets onto Public Storage’s operating platform. Post-value creation, the implied cap rate is really in the low- to mid-6% range.
Q: This deal seems more balanced between revenue and expense synergies than prior transactions. How does the approach compare to past deals?
A (Tom Boyle): We don’t want to compare directly to past potential transactions, but in completed deals, roughly half to three-quarters of the synergy opportunity typically comes from the revenue side, with the balance from expenses. This transaction is no different. What makes this one somewhat unique is that the NSA portfolio is operating at about 84% occupancy, leaving clear vacancy to fill over time.
Q: How did you decide which assets would go into the wholly owned bucket versus the high-cash-flow joint venture?
A (Tom Boyle): We evaluated the entire NSA operating portfolio and considered which assets best complemented the future Public Storage portfolio. We visited nearly every asset over the last several years and overlaid our proprietary data and data sets to determine which assets fit best in each bucket. Some core markets appear in both the wholly owned and JV portfolios, and we see upside in both.
Q: Why are you assuming only about half of NSA’s current G&A will be savings? Why wouldn’t the merger eliminate more overhead?
A (Joe Russell): We report both direct operating expenses and indirect operating expenses, with indirect costs equaling roughly 3% of revenue. NSA’s indirect costs are generally included within its G&A, so we analyzed all the off-site costs needed to run the NSA portfolio and determined what portion would remain as indirect operating expense after the deal. We have effectively taken out 100% of the group-level G&A while keeping the off-site property-management costs embedded in the portfolio.
Q: Are there any properties or regions in the combined portfolio that you might look to sell over time?
A (Tom Boyle): Yes, that is something we will explore over time. That is consistent with how Public Storage already thinks about its own portfolio, using a data-driven approach at the micro-market level to shape the portfolio for the future. We will provide updates later.
Q: Does the NSA portfolio need a new, multi-year Property of Tomorrow-style renovation program?
A (Tom Boyle): The properties already look good, but there is still an opportunity to bring them into the Public Storage brand and customer experience. That includes new signage, office updates and other branding-related improvements.
Q: Why was the new high-cash-flow joint venture formed instead of rolling all the assets into the wholly owned platform? Why use secured debt, and what fee streams should investors expect?
A (Tom Boyle): The new joint venture creates a win-win by offering participating OP unit holders a higher-yield private venture with more leverage than the public company, while still benefiting from the PS Next operating platform.
A (Joe Russell): The venture will have about $2.2 billion of debt against roughly $3.3 billion of value, equating to about 65% to 70% leverage. About $2 billion of that will be secured debt, initially funded with a committed bridge loan, and Public Storage will also provide more than $200 million of mezzanine financing. We expect to earn standard property-management and asset-management fees from the venture.
Q: Many of NSA’s Sun Belt markets were strong during COVID but have struggled recently due to supply pressure. What gives you confidence in these markets now?
A (Tom Boyle): “We have been seeing sequential improvement in many of those Sun Belt markets for several quarters. As the industry works through the unusually strong 2021 and 2022 demand comps and the supply that followed, fundamentals have been improving. New supply is slowing in most of those markets, and we have been thoughtful about the sequencing of synergy execution relative to improving fundamentals.”
Q: The direct NOI margin gap between PSA and NSA is about 880 basis points. Can you break down what is driving that big difference?
A (Joe Russell): The biggest driver is revenue. We expect 11% to 15% of incremental revenue growth on top of what the NSA portfolio would have achieved naturally, and 50% to 75% of the operating upside typically comes from the top line. We expect to close about 500 basis points of the roughly 900-basis-point gap, leaving the stabilized NSA margin about 400 basis points below PSA’s. We pressure-tested those assumptions from both top-down and bottom-up perspectives.
Q: There was not much discussion of demographics in the presentation. How do demographics factor into your view of these new markets?
A (Tom Boyle): We are absolutely using demographics in our evaluation. We took a very data-driven approach at the local submarket and micro-market level while also overlaying our on-the-ground understanding of the markets. That helps us assess both the long-term opportunity and the near-term value-creation potential.
Q: Can you talk more about the geographic overlap between PSA and the on-balance-sheet portion of NSA, and how that affects confidence in the upside?
A (Tom Boyle): About 80% of the new operating portfolio across all three buckets overlaps with Public Storage’s existing markets, while about 20% is in new markets. The overlap is even higher in the wholly owned portfolio.
A (Joe Russell): Scale is crucial. In Public Storage’s own portfolio, markets with critical density produce about a 600-basis-point margin advantage over those without it, adjusted for rent, which supports our confidence in closing the margin gap as scale increases in overlapping trade areas.
Q: How should we think about the $300 million of capex? How much goes to the consolidated portfolio versus the JV, and how much is true deferred maintenance versus rebranding?
A (Joe Russell): The spend is spread throughout the portfolio. We have toured most of the assets and have a good feel for what is needed. The capex goes beyond paint and deferred maintenance. It includes technology and operational upgrades needed to deliver Public Storage’s customer experience, such as gate access, digital code access, security systems, 24/7 monitoring and other infrastructure that supports e-rentals and staffing efficiency.
Q: With NSA’s existing joint ventures, do you plan to keep those 25% stakes and continue managing them, or is there a plan to buy out those institutional partners over time?
A (Tom Boyle): Those ventures have been successful, and we look forward to engaging with the capital partners and continuing those relationships. We plan to reach out after the transaction closes to explain why we are excited about the deal and what the combined company can bring to those partnerships.
Q: How does this transaction affect your external growth strategy going forward? Will acquisitions pause until the NSA portfolio is integrated?
A (Tom Boyle): The structure of the transaction preserves significant financial flexibility, allowing Public Storage to continue pursuing value creation beyond the NSA deal. We remain encouraged by what we are seeing in the transaction market, and we believe there could be more industry activity in 2026 than in 2025.
Q: Why is Public Storage interested in this portfolio now versus a couple years ago?
A (Tom Boyle): Now is an ideal time because the deal fits with the PS 4.0 strategy and offers a major value-creation opportunity. Adding NSA’s assets to the PS Next operating platform, bringing in more than 450,000 customers and welcoming the NSA team into Public Storage’s culture creates a strong launch point for the next era of Public Storage.
Q: Within comparable stores, how much of the performance gap between PSA and NSA comes from occupancy versus rate?
A (Joe Russell): We underwrote the portfolio market by market, and we believe occupancy can rise from the mid-80% range to around 90%. There is also meaningful rate opportunity from attracting new customers and retaining existing ones. We expect 11% to 15% of incremental revenue growth from applying the Public Storage brand and operating platform.
Q: For NSA, why is now the right time to sell? Why not remain independent if markets are beginning to recover?
A (David Cramer, NSA): The board and management spent a lot of time evaluating NSA’s long-term outlook and believed we were making progress independently. However, combining with Public Storage, given the strength of its platform, team and synergy opportunities, made strategic sense. The board sees this as a unique chance to accelerate toward our long-term goals.
Q: Can you talk about the magnitude and timing of potential dispositions and asset recycling?
A (Tom Boyle): This is something we will evaluate over time as we integrate the assets, improve performance and collect more operating data. There will likely be some modest dispositions from the newly acquired portfolio, and investors may also hear more about potential dispositions from the legacy Public Storage portfolio as we take a more data-driven approach to portfolio construction.
Q: Was the new joint venture something NSA’s OP holders were pushing for, or was it more about isolating part of the portfolio?
A (Tom Boyle): The JV creates a real win-win for both NSA stakeholders and the combined company by offering a different return profile that is attractive to all parties. The structure reflects both market-selection and capital-structure considerations, as well as the upside we believe we can generate through our operating platform.
