**The following was sent to employees of National Storage Affiliates Trust ("NSA") by Dave Cramer, Chief Executive Officer, on March 16, 2026, in connection with Public Storage's proposed acquisition of NSA.**

**1.** **What was announced? Why is Public Storage acquiring NSA?** 

&nbsp;&nbsp;&nbsp;&nbsp;· NSA has entered into a definitive agreement to be acquired by Public Storage
in an all-stock transaction.

&nbsp;&nbsp;&nbsp;&nbsp;· This transaction will bring together two complementary portfolios to create
a strong and efficient self-storage leader with increased scale.

&nbsp;&nbsp;&nbsp;&nbsp;· Together, we will be better positioned to continue serving our customers
and communities with the local care and commitment that differentiates NSA.

**2.** **Why now? Why is this the right time?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Over the past several years, we have successfully executed a strategic transformation
to fully integrate our operating platform, streamline our portfolio and strengthen our marketing, pricing and technology capabilities.

&nbsp;&nbsp;&nbsp;&nbsp;· As a result, today we are operating from a position of strength with positive
momentum underway.

&nbsp;&nbsp;&nbsp;&nbsp;· With a solid foundation in place, we believe that now is the right time to
take the next step forward with Public Storage.

&nbsp;&nbsp;&nbsp;&nbsp;· We are delighted that this transaction will deliver great value to NSA investors,
benefit our customers, and create exciting career development and advancement opportunities for many employees.

**3.** **Why Public Storage? What are the benefits of combining with them?** 

&nbsp;&nbsp;&nbsp;&nbsp;· This transaction is an exciting step forward for NSA and our family of brands.

&nbsp;&nbsp;&nbsp;&nbsp;· As the largest owner and operator of self-storage facilities in the world,
Public Storage brings scale, resources and global expertise to support our next chapter of growth.

&nbsp;&nbsp;&nbsp;&nbsp;· By joining our complementary portfolios, we will create a stronger operating
platform with greater reach across key markets.

**4.** **What should I know about Public Storage?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Public Storage is the largest owner and operator of self-storage properties
globally. The combined company will have unparalleled scale, with ~4,600 stores spanning 327 million square feet in 42 states.

&nbsp;&nbsp;&nbsp;&nbsp;· Over the past four decades, Public Storage has built a premier brand that
serves two million customers every day, with an unparalleled digital-first customer experience and industry-leading financial performance.
They are proud to support nearly 6,000 team members with an award-winning "Own It" culture and rewarding career opportunities.

**5.** **How do the cultures of the companies compare?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Public Storage and NSA have highly complementary cultures with similar values
centered around integrity, accountability and dedication to customer service.

&nbsp;&nbsp;&nbsp;&nbsp;· Like us, Public Storage is an employee-driven organization committed to fostering
a workplace of respect and empowerment.

&nbsp;&nbsp;&nbsp;&nbsp;· We are excited to join an organization that supports employees and advances
our shared commitment to delivering the best customer experience.

**6.** **What does this transaction mean for employees?** 

&nbsp;&nbsp;&nbsp;&nbsp;· At NSA, our people are our most valuable asset, and Public Storage recognizes
that our employees are the driving force behind the Company's success.

&nbsp;&nbsp;&nbsp;&nbsp;· As such, we expect that nearly all field employees and many corporate employees
will be offered roles in the combined company following close of the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;· We also anticipate that this transaction will provide additional opportunities
for employees as part of a larger organization with expanded resources and reach.

&nbsp;&nbsp;&nbsp;&nbsp;· Together, we expect to have the opportunity to expand digital and AI-led
customer experiences, bring the power of second-to-none self-storage to more customers and share best practices with new colleagues.

**7.** **What changes should we expect? Does this announcement have any impact on day-to-day responsibilities or reporting structure?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Until the transaction closes, which we expect to occur in the third quarter
of 2026, NSA and Public Storage will continue to operate as separate, independent companies.

&nbsp;&nbsp;&nbsp;&nbsp;· As of now, it is business as usual at NSA. The majority of our employees
should not expect any changes to roles, responsibilities or reporting structure as a result of the transaction announcement.

&nbsp;&nbsp;&nbsp;&nbsp;· It's important to remember that this announcement is just the first
step in the process, and there are still many details that will be determined over the coming months as we develop integration plans.

&nbsp;&nbsp;&nbsp;&nbsp;· We will keep you informed as decisions are made.

**8. What professional development opportunities will Public Storage offer at our properties?**

&nbsp;&nbsp;&nbsp;&nbsp;· Over the last two years, Public Storage has provided more than 1,000 team
members with promotion or internal transfer opportunities. They offer tremendous coaching opportunities and even a path to management!

&nbsp;&nbsp;&nbsp;&nbsp;· For property-level team members, career paths consist of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Key Training Professional (KTP) – Train new hires and expand coaching skills

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o District Delinquency Manager (DDM) – District operational and risk management, while continuing to serve in the Property Manager

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o District Manager in Training (DMIT) – Growth into management

&nbsp;&nbsp;&nbsp;&nbsp;· They also offer remote opportunities for property employees to join their
Customer Care Center which is over three hundred people strong today. These positions have additional opportunities for advancement and
growth:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Customer Service Specialist to Sales Agent – Acquire sales skills and techniques

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Property Operations Specialists (PrOS) – Remote property management, helping our customer in the field

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Customer Service Supervisor – Growth into management

**8.** **Will there be any layoffs or organizational changes?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Public Storage's #1 priority is doing right by customers and serving
them with the highest-quality experience possible. Our team will be essential to that work as the combined company manages the largest
self-storage portfolio in the world.

&nbsp;&nbsp;&nbsp;&nbsp;· That said, we expect that nearly all field employees and many corporate employees
will be offered roles in the combined company following close of the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;· Overall, we think this transaction will create exciting career development
and advancement opportunities for many employees.

&nbsp;&nbsp;&nbsp;&nbsp;· Remember that we just announced this transaction, and there are still many
decisions to be made.

of NSA and Public Storage to design a thoughtful integration plan as we work to seamlessly bring our two companies together.

**9.** **Are there any changes to compensation and benefits?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Until the transaction closes, we are operating as normal, and employees should
not expect changes to compensation packages or benefits.

&nbsp;&nbsp;&nbsp;&nbsp;· As part of the integration process, leaders from NSA and Public Storage will
make decisions about how we will operate following the close of the transaction, including with respect to go-forward compensation plans.

&nbsp;&nbsp;&nbsp;&nbsp;· We will provide more detail as and when appropriate.

**10.** **What are the next steps to completing the transaction? What should I expect between now and then?** 

&nbsp;&nbsp;&nbsp;&nbsp;· The transaction, which is expected to close in the third quarter of 2026,
is subject to the approval of NSA equity holders, and satisfaction of other customary closing conditions.

&nbsp;&nbsp;&nbsp;&nbsp;· Until then, NSA and Public Storage will operate as separate, independent
companies.

&nbsp;&nbsp;&nbsp;&nbsp;· We will soon begin integration planning with the Public Storage team to prepare
for a smooth integration after close.

&nbsp;&nbsp;&nbsp;&nbsp;· In the meantime, we ask that you remain focused on your existing priorities
and continue to serve our customers and communities with the care and commitment they expect from us.

**11.** **What is happening to NSA's leadership team? Who will lead the combined company?** 

&nbsp;&nbsp;&nbsp;&nbsp;· Following the close of the transaction, Public Storage's recently promoted
CEO, Tom Boyle, will continue to serve in that role and the Public Storage leadership team will remain in place.

&nbsp;&nbsp;&nbsp;&nbsp;· Additional members of the combined company's team will be communicated
as decisions are made.

**12.** **What will the combined company be called?**

to trade on the New York Stock Exchange under the ticker symbol "PSA" upon completion of the transaction.

**13.** **What will happen to the NSA name and brand? Will any facilities be closed?** 

&nbsp;&nbsp;&nbsp;&nbsp;· It is still early in the process, and there are many details to be worked
through as we develop our integration plans.

&nbsp;&nbsp;&nbsp;&nbsp;· That said, over time, we expect that our stores will be rebranded as Public
Storage locations following the close of the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;· We will continue to be transparent and keep you informed as appropriate as
the process unfolds.

**14.** **I live on-site at the facility. Will I still be able to remain in the unit?** 

&nbsp;&nbsp;&nbsp;&nbsp;· While we don't expect any significant changes, it's important
to remember that we just announced this transaction, and there are still many decisions to be made.

&nbsp;&nbsp;&nbsp;&nbsp;· We will work closely with Public Storage in the weeks and months ahead to
determine how on-site employee housing arrangements will be handled. We are able to confirm that Public Storage does allow employees to
live on-site.

&nbsp;&nbsp;&nbsp;&nbsp;· As a reminder, we expect that nearly all field employees and many corporate
employees will be offered roles in the combined company following the close of the transaction.

companies.

combination with Public Storage employees.
