/Admin/ADVANCED GRAPHICS FILES/Cover and Template/2024/2024_01/4159141-001_Trevor McMillin_SmartStop_Cover & Template C O N F I D E N T I A L COLOR PALETTE Text Additional Information Regarding NOI and Adjusted EBITDA 50 56 62 Title bar/Bullets 1 124 186 Net Operating Income or ("NOI") ACCENTS NOI is a non-GAAP measure that SmartStop defines as net income (loss), computed in accordance with GAAP, generated from properties, excluding tenant protection plan revenue, before corporate general and administrative expenses, asset management fees, interest expense, depreciation, amortization, acquisition expenses, tenant protection economics, stock compensation related to our IPO Grant and other non-property 1 126 related income and expense. SmartStop believes that NOI is useful for investors as it provides a measure of the operating performance of its operating assets because NOI excludes certain items that are not associated 124 211 1 with the ongoing operation of the properties. Additionally, SmartStop believes that NOI is a widely accepted measure of comparative operating performance in the real estate community. However, SmartStop's use of the 186 254 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 127 212 operations, or other related financial measures, in evaluating our operating performance. 188 253 2 3 129 Adjusted EBITDA Adjusted EBITDA is a non-GAAP measure that SmartStop defines as net income (loss) computed in accordance with GAAP before: (i) interest expense and net loss on extinguishment of debt; (ii) tax related expenses; (iii) 32 140 depreciation and amortization; (iv) adjustments to reflect EBITDA related to its unconsolidated entities; (v) changes in the fair value of its contingent earn-out liability; (vi) acquisition and transaction expenses; (vii) 56 168 3 impairment charges related to goodwill, intangible assets, and equity investments; (viii) equity based compensation expense; (ix) gains or losses from disposition of depreciable property; (x) gains or losses from the 100 218 acquisition of previously unconsolidated affiliates; (xi) sponsor funding revenue reduction; (xii) offering related expenses; and (xiii) gains or losses from foreign currency and interest rate derivatives. SmartStop uses Adjusted EBITDA as an additional metric by which it measures its operational performance independent of the impact of its capital structure.

Adjusted EBITDA should be reviewed in conjunction with other measurements as an indication of SmartStop's performance. 166 219 166 219 5 166 219 1 126 Hyperlink 124 211 186 254 127 212 Followed 188 253 Hyperlink 3 129 TABLE 50 56 Lines 62 1 124 Highlights 186 44
