Strategic Storage Trust VI, Inc. ("SST VI"), a publicly registered non-traded real estate investment trust sponsored by an affiliate of SmartStop Self Storage REIT, Inc. ("SmartStop") (NYSE:SMA), announced operating results for the year ended December 31, 2025.

"Our performance this year reflects the strength of both our Sponsor's operating platform, our disciplined growth strategy and our strategic allocation to high performing Canadian assets," commented H. Michael Schwartz, President and CEO of Strategic Storage Trust VI, Inc. "Year-to-date, total revenues increased by 8.8%, driven in part by continued momentum in our same-store portfolio, where revenues grew 4.6% and net operating income increased 8.6%. These results underscore our ability to drive meaningful operating leverage while maintaining a strong focus on pricing, occupancy, and expense management. Equally important is the progress we've made on the development front. Over the past year, we successfully brought four of our Canadian joint venture properties online, expanding our footprint in the Greater Toronto Area and Quebec, Canada. While these assets are still in their initial lease-up phase, with average occupancy of approximately 41% as of year-end, we are encouraged by early demand trends and expect these properties to be a meaningful contributor to future growth as they stabilize. In addition, subsequent to year-end, we completed construction and commenced operations at our wholly owned development property in Ontario, Canada another important milestone that reflects our ability to execute on high-quality, strategically located projects."

Same-Store Facility Results - Years ended December 31, 2025 and 2024

The following table sets forth operating data for our same-store facilities (stabilized and comparable properties that have been included in the consolidated results of operations since January 1, 2024) for the years ended December 31, 2025 and 2024. We consider the following data to be meaningful as this allows for the comparison of results without the effects of acquisition, lease up, or development activity.

Our increase in same-store revenue of approximately $0.6 million was primarily the result of an increase in revenue per occupied square foot of approximately 3.2% for the year ended December 31, 2025 over the year ended December 31, 2024 offset by a decrease in average physical occupancy of approximately 1.0%.

Our same-store property operating expenses decreased by approximately $60,000 or 1.1% for the year ended December 31, 2025 compared to the year ended December 31, 2024.

Net operating income, or NOI, is a non-GAAP measure that we define as net income (loss), computed in accordance with GAAP, generated from properties before corporate general and administrative expenses, asset management fees, interest expense, depreciation, amortization, acquisition expenses, tenant protection economics, and other non-property related income and expense. We believe that NOI is useful for investors as it provides a measure of the operating performance of our operating assets because NOI excludes certain items that are not associated with the ongoing operation of the properties. Additionally, we believe that NOI (sometimes referred to as property operating income) is a widely accepted measure of comparative operating performance in the real estate community. However, our use of the term NOI may not be comparable to that of other real estate companies as they may have different methodologies for computing this amount. In addition, NOI is not a substitute for net income (loss), cash flows from operations, or other related financial measures, in evaluating our operating performance.

The following table presents a reconciliation of net loss as presented on our consolidated statements of operations to NOI, as stated above, for the periods indicated:
