VISION

We are an inspired, engaged and collaborative team committed to providing extraordinary service to our residents, customers and each other.

CULTURE

Live the Golden RuleDo the right thingWe over me
Treat others the way you want to be treated – we don’t just practice it, we live it. The exceptional experiences we deliver wouldn’t be possible without understanding our impact on others. We operate with respect, empathy and consideration at all times. It’s not a suggestion, it’s our moral obligation.We choose honesty and integrity in all our actions, making the best, most educated decisions we can. Sometimes the right thing is the easy thing, or the popular thing. Other times it isn’t. We don’t get sidetracked when things go wrong, and we don’t shy away from doing what is right.We work as a collaborative and collective unit. No one person operates alone, and we keep the wider team in mind when making decisions about individual work. We know we need each other to produce an unmatched experience for our residents and customers. What’s more, we trust each other enough to sacrifice our own goals for those of the team.
Nothing changes if nothing changesMindset is everythingKeep it simple
Mindset is the guiding force behind all our actions. We can’t always decide what happens to us, but we can always decide how to handle it. Bad experiences don’t bring down our whole day. We learn, we grow and we become resilient. We are successful because we choose to be, every day and every step of the way.Let’s not overcomplicate things. Can a clearer word explain your point? Use it. Can fewer steps streamline your work? Do it. We lead with what is most important, shedding complexity as we go. Simplicity isn’t effortless, but it does make things a bit easier.
We don’t sit still for long. We are constantly transforming both our industry and our company. That means we are open and flexible, using what works now to develop what works next. Even if it ain’t broke, we still make it better. Lots of folks will say it hasn’t been done – we say it hasn’t been done yet.
Be yourself & thrive
Inclusion, diversity, equity and accessibility are at the heart of who we are and what we do. Our biggest competitive advantage is the variety of individual perspectives we all bring to Sun. We support and celebrate what makes us unique, creating a space where all can succeed.

Dear Fellow Shareholders,

Throughout 2024 Sun aimed to simplify our business, focus on our portfolio’s durable income streams, and improve our balance sheet. We made notable progress throughout the year and added to our achievements with the February 2025 announcement of the agreement to sell Safe Harbor Marinas to Blackstone Infrastructure. Safe Harbor was an excellent investment for Sun and the sale at this time allows us to achieve several of our strategic objectives, most notably refocusing on our core MH and RV segments and meaningfully improving our leverage profile, while realizing a very attractive return. Sun returns to being a pure-play owner and operator of best-in-class manufactured housing and RV communities, supported by a strong balance sheet.

2024 Results

In 2024, Sun once again delivered strong results in our Manufactured Housing segment, demonstrating the ongoing demand for attainable housing. On the RV side we have remained focused on continuing to increase the contribution from real property and annual income streams. For the full year, approximately 70% of our revenue producing site gains came from RV transient to annual conversions. We also worked to better align expenses with their respective revenue streams. In the UK, positive sales momentum continued, with strong unit sales which in turn drive real property income.

A key priority for Sun has been focusing on our core portfolio through the selective disposition of non-strategic assets and reduction of capital expenditures. For 2024 and through our fourth quarter earnings release on February 26, 2025, we completed total dispositions of approximately $570 million including $180 million in the fourth quarter and year to date 2025. We also reduced non-recurring capital expenditures, which decreased nearly 50%, from 2023 to 2024.

Governance and CEO Retirement

We further enhanced our governance through board refreshment. Over the last 12 months, we added two new members to our board of directors, had two longer serving Board members step down, and announced additional planned refreshment. In March 2025, we announced the nomination of Mark A. Denien as an independent director candidate for election at the upcoming annual meeting of shareholders. Additionally, in November 2024, Gary announced his intention to retire in 2025. The board search committee continues its comprehensive search process and we will provide an update at the appropriate time.

In Closing

We are confident in the favorable dynamics and durable income streams of our core businesses and are encouraged with our outlook. Furthermore, we continue to implement our operating initiatives which focus on maximizing top-line revenue growth to drive bottom-line operational results. We have a clear strategic direction, focused on realizing the full potential of our portfolio and platform.

Thank you for your continued support.

Sincerely,

Gary A. ShiffmanChairman and CEOClunet R. LewisLead Independent Director
