LETTER TO OUR SHAREHOLDERS Dear Fellow Shareholders, We enter 2026 positioned to build on Sun’s strong operational and cultural legacy and create value for our shareholders. In 2025, we successfully executed on our strategic objectives, simplifying our business and strengthening our balance sheet. With the closing of the Safe Harbor Marinas sale and other non-strategic assets, we sharpened our focus on our core manufactured housing (MH) and recreation vehicle (RV) segments. Importantly, we deployed the proceeds deliberately through a thoughtful capital allocation process, meaningfully enhancing our balance sheet position and financial flexibility. 2025 RESULTS Our disciplined execution of our strategic priorities was reflected in our strong 2025 results. In addition to optimizing our portfolio, we significantly enhanced our capital deployment strategy by using the proceeds from the Safe Harbor sale to reposition our balance sheet. We paid down more than $3 billion of debt and fully eliminated our floating-rate debt exposure. We also returned capital to shareholders through share repurchases, a special cash distribution, and a meaningful increase to our quarterly dividend. On the strategic investment front, we acquired fourteen MH and annual RV communities within existing Sun geographies. In the UK, we acquired the ground leases for 32 properties, resulting in Sun owning the full freehold interest across our UK portfolio, reducing lease complexity while creating meaningful financial and strategic flexibility. BOARD AND MANAGEMENT As we advanced our strategic and financial priorities, we also strengthened our leadership team and further enhanced our Board of Directors. In October 2025, Charles Young joined Sun as both our Chief Executive Officer and director. At the Board level, Mark Denien was elected to the Board in 2025 as an independent director and, after decades of distinguished and dedicated service to the Company and our shareholders, Clunet Lewis will retire from the Board this year. LOOKING AHEAD We remain committed to creating long-term value for our shareholders. Building on the successes of 2025, we expect to continue to take purposeful, measured actions to support and further strengthen our core business and seek to deliver reliable earnings growth. With a clear strategic direction, we remain focused on realizing the full potential of our portfolio and platform. Thank you for your continued support. Sincerely, GARY A.
