Disclaimer & Risk Factors Certain of the matters discussed in this investor presentation constitute forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “anticipate,” “estimate,” “believe,” “continue,” or other similar words. Readers are cautioned not to place undue reliance on these forward-looking statements and any such forward-looking statements are qualified in their entirety by reference to the following cautionary statements. Any such forward-looking statements are based on current expectations, estimates and projections about the industry and markets in which we operate, and beliefs of, and assumptions made by, our management and involve uncertainties that could significantly affect our financial results. Such statements include, but are not limited to: (i) statements about our plans, strategies, initiatives, and prospects; and (ii) statements about our future results of operations, capital expenditures, and liquidity. Such statements are subject to known and unknown risks and uncertainties, which could cause actual results to differ materially from those projected or anticipated, including, without limitation: (i) adverse changes in economic conditions in the real estate industry and in the markets in which we own and operate self storage properties; (ii) market trends in our industry, interest rates, inflation, the debt and lending markets or the general economy; (iii) failure to realize the benefits from affiliated mergers, acquisitions and other strategic transactions; (iv) the current concentration of our rental income in Florida, California and the Greater Toronto Area of Canada; (v) the effect of competition at our self storage properties or from other storage alternatives, which could cause rents and occupancy rates to decline; (vi) the impact of our outstanding Series A Convertible Preferred Stock, which ranks senior to all common stock and grants the holder superior rights compared to common stockholders, and may have the effect of diluting our stockholders’ interests in us and discouraging a takeover or other similar transaction; (vii) impacts on our business due to certain of our officers and key personnel facing competing demands relating to their time and conflicts of interest as a result of the positions they hold with affiliated entities; (viii) the impact of investments in or loans to our Managed REITs; (ix) revenue and earnings from the Managed REIT Platform; (x) increases in property taxes; (xi) the impact of and changes in national, state, and local laws and regulations including, without limitation, those governing real estate investment trusts, environmental matters, taxes, insurance, accounting guidance and other aspects of our business; (xii) impacts of changes in the Canadian Dollar/USD exchange rate, which could have a material adverse effect on our operating results; (xiii) the degree to which our hedging strategies may or may not protect us from interest rate volatility; (xiv) risks associated with data breaches, including cybersecurity attacks or other unauthorized access or misuse of information, any of which could adversely affect our business and results; (xv) potential environmental or other liabilities; (xvi) risks related to or a consequence of natural disasters or acts of violence, pandemics, terrorism, insurrection or war that affect the markets in which we operate; (xvii) failure to continue to qualify as a REIT for U.S. federal income tax purposes. Actual results may differ materially from those indicated by such forward-looking statements. In addition, the forward-looking statements represent SmartStop’s views as of the date on which such statements were made. SmartStop anticipates that subsequent events and developments may cause its views to change. These forward-looking statements should not be relied upon as representing SmartStop’s views as of any date subsequent to the date hereof. Additional factors that may affect the business or financial results of SmartStop are described in the risk factors included in SmartStop’s filings with the SEC, including SmartStop’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as supplemented by the risk factors included in Part II, Item 1A of its Quarterly Reports on Form 10-Q, which factors are incorporated herein by reference, all of which are filed with the SEC and available at www.sec.gov. SmartStop expressly disclaims a duty to provide updates to forward-looking statements, whether as a result of new information, future events or other occurrences. This is neither an offer nor a solicitation to purchase securities. See our most recent Annual Report on Form 10-K and subsequent Form 10-Qs for specific risks associated with an investment in SmartStop Self Storage REIT, Inc. As of September 30, 2023, our accumulated deficit was approximately $166.2 million and it is possible that our operations may not be profitable in 2023. We have paid distributions from sources other than our cash flows from operations, including from the net proceeds of our public offering and our distribution reinvestment plan (DRP offering). We are not prohibited from undertaking such activities by our charter, bylaws or investment policies, and we may use an unlimited amount from any source to pay our distributions. For the twelve months ended December 31, 2021, we funded 92% of our distributions using cash flow from operations and 8% using proceeds from our DRP offering. For the 12 months ended December 31, 2022, we funded 100% of our distributions using cash flow from operations. No public market currently exists for shares of our common stock and there may never be one. Therefore, it will be difficult for our stockholders to sell their shares. Our charter does not require us to pursue a liquidity transaction at anytime. If you sell your shares, it will likely be at a substantial discount. We may only calculate the value per share for our shares annually and, therefore, you may not be able to determine the net asset value of your shares on an ongoing basis. We cannot assure our stockholders that we will be successful in the marketplace. Revenues and earnings from Strategic Storage Trust VI, Inc. and Strategic Storage Growth Trust III, Inc. (the “Managed REITs”) are uncertain. Because the revenue streams from the advisory agreements with the Managed REITs are subject to limitation or cancellation, any such termination could adversely affect our financial condition, cash flow and the amount available for distributions to you. We will face conflicts of interest relating to the purchase of properties, including conflicts with the Managed REITs, and such conflicts may not be resolved in our favor, which could adversely affect our investment opportunities. Our trademarks are important to the value of our business, and the ability to protect, and costs associated with protecting, our intellectual property could adversely affect our business and results of operations. We may incur substantial debt, which could hinder our ability to pay distributions to our stockholders or could decrease the value of your investment. Our Series A Preferred Shares rank senior to our common stock, and therefore, any cash we have to pay distributions will be used to pay distributions to the holders of Series A Preferred Shares first, which could have a negative impact on our ability to pay distributions to our common stockholders. We may fail to qualify as a REIT, which could adversely affect our operations and our ability to make distributions. Our board of directors may change any of our investment objectives without your consent. We use market data throughout this presentation that has generally been obtained from publicly available information and industry publications. We have also obtained certain information, where indicated, from the 2022 Self Storage Almanac and the May 2021 Colliers Report. These sources generally state that the information they provide has been obtained from sources believed to be reliable, but the accuracy and completeness of the information are not guaranteed. The market data includes forecasts and projections that are based on industry surveys and the preparers’ experiences in the industry, and there is no assurance that any of the projections or forecasts will be achieved. We believe that the surveys and market research others have performed are reliable, but we have not independently verified this information. This presentation may contain trade names, trademarks or service marks of other companies. The Company does not intend the use or display of other parties’ trade names, trademarks or service marks to imply a relationship with, or endorsement or sponsorship of, these other parties. This presentation includes certain financial information that is not presented in accordance with generally accepted accounting principles in the United States (“GAAP”). Such non-GAAP financial measures should not be considered alternatives to net income as a performance measure or cash flows from operations as reported on our statement of cash flows as a liquidity measure and should be considered in addition to, and not in lieu of, GAAP financial measures. Please refer to the Appendix of this presentation for a reconciliation of the non-GAAP financial measures included in this presentation to the most directly comparable financial measures prepared in accordance with GAAP. You should be aware that SmartStop’s presentation of these and other non-GAAP financial measures in this presentation may not be comparable to similarly-titled measures used by other companies. Non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. We seek to compensate such limitations by providing a detailed reconciliation for the non-GAAP financial measures to the most directly comparable financial measures stated in accordance with GAAP in this presentation. You are encouraged to review the related GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.

Reconciliation: Net Income (Loss) to Net Operating Income

Non-GAAP Reconciliations (continued) This gain relates to the mark up in fair value of our preexisting equity interests in SSGT II as a result of our acquisition of control in the SSGT II Merger. This represents the portion of the above stated adjustments in the calculations of FFO and FFO, as adjusted, that are attributable to our noncontrolling interests. These items represent the amortization, accretion, or adjustment of intangible assets or deferred tax liabilities. This represents acquisition expenses associated with investments in real estate that were incurred prior to the acquisitions becoming probable and therefore not capitalized in accordance with our capitalization policy. The contingent earnout adjustment represents the adjustment to the fair value during the period of the Class A-2 Units issued in connection with the self administration transaction. The net loss associated with the extinguishment of debt includes prepayment penalties, defeasance costs, the write-off of unamortized deferred financing fees, and other fees incurred. This represents the mark-to-market adjustment for our derivative instruments not designated for hedge accounting and the ineffective portion of the change in fair value of derivatives recognized in earnings, as well as changes in foreign currency related to our foreign equity investments not classified as long term. Such costs relate to our filing of an S-11 registration statement and our pursuit of a potential offering of our common stock. As this item is non-recurring and not a primary driver in our decision-making process, FFO is adjusted for its effect to arrive at FFO, as adjusted, as a means of determining a comparable sustainable operating performance metric.

Non-GAAP Reconciliations (continued) This represents the portion of the above stated adjustments in the calculations of FFO and FFO, as adjusted, that are attributable to our non-controlling interests. Includes all Class A Shares, Class T Shares and OP Units, as well as the dilutive effect on FFO and FFO, as adjusted of both unvested restricted stock and long term incentive plan units (both time-based units and performance based-units), and is calculated using the two-class, treasury stock or if-converted method, as applicable. The outstanding convertible preferred stock was excluded as the conversion of such shares was antidilutive to FFO and FFO, as adjusted. This excludes Class A-2 OP Units, the conversion of which is contingent on growth in assets under management or other contingent events before being converted to a class of OP Units equivalent to a common share.

Reconciliation: Net Income (Loss) to Adjusted EBITDA: Trailing 5 Quarters Tax related expense consists primarily of adjustments to deferred tax liabilities, state, federal, and Canadian income tax, as well as state franchise taxes. The contingent earnout adjustment represents the adjustment to the fair value of the Class A-2 Units issued in connection with the self administration transaction. This represents acquisition expenses associated with investments in real estate that were incurred prior to the acquisitions becoming probable and therefore not capitalized in accordance with our capitalization policy.

Additional Information Regarding FFO & FFO, as adjusted and NOI Funds from Operations (“FFO”) and FFO, as adjusted Funds from operations (“FFO”) is an industry wide metric promulgated by the National Association of Real Estate Investment Trusts, or NAREIT, which SmartStop believes to be an appropriate supplemental measure to reflect the operating performance of a REIT. The use of FFO is recommended by the REIT industry as a supplemental performance measure. SmartStop defines FFO, a non-GAAP measure, consistent with the standards established by the White Paper on FFO approved by the Board of Governors of NAREIT, or the White Paper. The White Paper defines FFO as net income (loss) computed in accordance with GAAP, excluding gains or losses from sales of property and asset impairment write downs, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Additionally, gains and losses from change in control are excluded from the determination of FFO. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. SmartStop’s FFO calculation complies with NAREIT’s policy described above. SmartStop uses FFO, as adjusted, as an additional non-GAAP financial measure to evaluate its operating performance. SmartStop previously used Modified Funds from Operations (“MFFO”) (as defined by the Institute for Portfolio Alternatives) as a non-GAAP measure of operating performance. Management replaced the MFFO measure with FFO, as adjusted, because FFO, as adjusted, provides investors with supplemental performance information that is consistent with the performance models and analysis used by management. In addition, FFO, as adjusted, is a measure used among SmartStop’s peer group, which includes publicly traded REITs. Further, SmartStop believes FFO, as adjusted, is useful in comparing the sustainability of its operating performance with the sustainability of the operating performance of other real estate companies. In determining FFO, as adjusted, SmartStop makes further adjustments to the NAREIT computation of FFO to exclude the effects of non-real estate related asset impairments and intangible amortization, acquisition related costs, other write-offs incurred in connection with acquisitions, contingent earnout expenses, adjustments of fair value of debt adjustments, gains or losses from extinguishment of debt, accretion of deferred tax liabilities, realized and unrealized gains/losses on foreign exchange transactions, and gains/losses on foreign exchange and interest rate derivatives not designated for hedge accounting, which SmartStop believes are not indicative of the Company’s overall long-term operating performance. SmartStop excludes these items from GAAP net income to arrive at FFO, as adjusted, as they are not the primary drivers in its decision-making process and excluding these items provides investors a view of its continuing operating portfolio performance over time and makes its results more comparable period to period and to other REITs, which in any respective period may experience fluctuations in such acquisition, merger or other similar activities that are not of a long-term operating performance nature. FFO, as adjusted, also reflects adjustments for unconsolidated partnerships and jointly owned investments. SmartStop uses FFO, as adjusted, as one measure of operating performance when SmartStop formulates corporate goals and evaluate the effectiveness of its strategies. Presentation of FFO and FFO, as adjusted, is intended to provide useful information to investors as they compare the operating performance of different REITs, although it should be noted that not all REITs calculate FFO and FFO, as adjusted, the same way, so comparisons with other REITs may not be meaningful. Furthermore, FFO and FFO, as adjusted, are not necessarily indicative of cash flow available to fund cash needs and should not be considered as an alternative to net income (loss) or income (loss) from continuing operations as an indication of SmartStop’s performance, as an alternative to cash flows from operations, which is an indication of liquidity, or indicative of funds available to fund SmartStop’s cash needs including SmartStop’s ability to make distributions to its stockholders. FFO and FFO, as adjusted, should not be considered as an alternative to net income (determined in accordance with GAAP) and should be reviewed in conjunction with other measurements as an indication of SmartStop’s performance. Neither the SEC, NAREIT, nor any other regulatory body has passed judgment on the acceptability of the adjustments that SmartStop uses to calculate FFO or FFO, as adjusted. In the future, the SEC, NAREIT or another regulatory body may decide to standardize the allowable adjustments across the publicly registered, non-traded REIT industry and SmartStop would have to adjust its calculation and characterization of FFO or FFO, as adjusted. Net Operating Income or (“NOI”) NOI is a non-GAAP measure that SmartStop defines 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 and other non-property related expenses. 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 with the ongoing operation of the properties. Additionally, SmartStop believes that NOI (also referred to as property operating income) is a widely accepted measure of comparative operating performance in the real estate community. However, SmartStop’s 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.
