("SmartStop") (NYSE:SMA), announced that it was recognized by Robert A. Stanger & Co., Inc. ("Stanger") as the top performing Lifecycle REIT over a three-year period as of March 31, 2026.

"We are proud of the continued growth and performance of our platform and the value we strive to deliver to our stockholders through a disciplined investment and operational strategy," said H. Michael Schwartz, President and CEO of SST VI. "We believe this recognition reflects the strength and resilience of the self-storage sector, the quality of our portfolio and the dedication of our team across the organization. During the pandemic-era boom, when much of the sector was characterized by aggressive development assumptions and compressed valuations, we focused on strategically positioning our portfolio — targeting underserved growth markets in the U.S. and expanding into Canada through our sponsor's platform. Being recognized as a top performer among Lifecycle REITs reinforces our long-term approach to building a high-quality platform focused on operational excellence and sustained value creation for investors."
