AND SUBSIDIARIES COMPUTATION OF SAME-STORE OPERATING RESULTS (UNAUDITED) Same-Store Facility Results - Three Months Ended June 30, 2026 and 2025 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, 2025) for the three months ended June 30, 2026 and 2025. 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.

76 (1) Revenue includes rental revenue, ancillary revenue, administrative and late fees. (2) Property operating expenses exclude corporate general and administrative expenses, asset management fees, interest expense, depreciation, amortization expense and acquisition expenses, but includes property management fees. (3) Of the total rentable square feet, parking represented approximately 199,780 square feet as of June 30, 2026 and 2025. On a same-store basis, for the same periods, parking represented approximately 109,000 square feet. (4) Determined by dividing the sum of the month-end occupied square feet for the applicable group of facilities for each applicable period by the sum of their month-end rentable square feet for the period.

(5) Determined by dividing the aggregate realized rental income for each applicable period by the aggregate of the month-end occupied square feet for the period. Properties are included in the respective calculations in their first full month of operations, as appropriate.

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. STRATEGIC STORAGE TRUST VI, INC.
