Current report

SmartStop OP, L.P. (our “Operating Partnership”) owns, directly or indirectly through one or more subsidiaries, all of the self storage properties that we own. As the sole general partner of our Operating Partnership, we have the exclusive power to manage and conduct the business of our Operating Partnership. As of September 30, 2026, we owned approximately 93.4% of the common units of limited partnership interests of our Operating Partnership (“OP Units”).

Current report

As of September 30, 2026, we provided third party management services to approximately 230 operating self storage properties, consisting of approximately 111,000 units and 17.0 million rentable square feet (the “Third Party Platform”).

Current report

We have provided financing to the Managed REITs in the form of mezzanine loans, bridge loans, promissory notes, and preferred equity, as applicable. We intend to continue in this practice going forward, if necessary. We continue to look to further expand our lending practice to include self storage facilities outside of the Managed REITs, including third party managed properties and joint venture properties. During 2026, we entered into a joint venture with AXCS Capital, Inc. (“AXCS”), a real estate lending joint venture, through which we make structured debt and preferred equity investments in the self storage sector, targeting self storage owners in the United States (the “AXCS Joint Venture”). The AXCS Joint Venture has begun, and intends to continue, to deploy capital across the full spectrum of structured capital solutions, including senior loans, mezzanine financing, preferred equity, and hybrid instruments. Target investment scenarios include ground-up development financing, value-add acquisitions and conversions, and recapitalizations of existing assets requiring bridge capital.

Current report

On September 29, 2026, we agreed to an investment of approximately $74.3 million CAD (approximately $52.3 million USD as of September 30, 2026) into a Canadian joint venture fund, subject to various closing and other conditions. The investment will provide us with a 50% general partner interest in the fund and an immediate expected approximate 34% limited partnership interest in the fund that we expect will own at close, or shortly thereafter, 14 self storage properties in Canada, comprising approximately 961,000 net rentable square feet and 9,600 units. The portfolio is in early lease-up and is approximately 50% physically occupied. The investment is structured as approximately (i) $49.3 million CAD of limited partnership interests and (ii) $25.0 million CAD of convertible preferred partnership interests bearing a 6.5% rate to be paid quarterly in-kind, convertible (at the election of the other shareholders of the general partner) to limited partnership interests in stages over the 24 months following the closing at the net asset value of the fund established at close. Our limited partnership interest in the Canadian joint venture fund would represent approximately 44%, assuming all of the convertible preferred equity was converted. We also committed to make additional investments of up to $228.0 million CAD (approximately $160.5 million USD as of September 30, 2026) during the three years following the closing, primarily to fund additional self storage properties that may be acquired by the fund, all subject to the approval of the general partner of the fund. Within that amount, it is contemplated that approximately $5.0 million CAD may be requested for working capital and other permitted general purposes of the fund, and up to approximately $10.0 million CAD may be requested in connection with refinancings of fund indebtedness and other long-term items. Any such additional investment, including those working capital and refinancing amounts, requires general partner approval, which requires our separate specific approval in our capacity as a shareholder of the general partner, and the same approval of one of the other shareholders. However, if the fund’s pending sale of one of its existing properties is not completed within 30 days following the closing, we will be required, without any further approval on our part, to contribute the amount of working capital that the fund’s general partner, acting reasonably, determines the fund requires as a result of continuing to hold that property, which contribution would count against the $228.0 million CAD additional investment amount.

Current report

In connection with the investment, we expect to provide guarantees directly to certain lenders of the fund’s subsidiaries, proportionate to our common ownership interest in the fund.

Current report

The investment and related transactions pertaining to this closing are subject to approval under the Canadian Competition Act and certain other closing conditions customary in transactions of this nature. Due to these closing conditions, we cannot make any assurances that the investment and related transactions pertaining to this closing will occur.

Current report

As of September 30, 2026, we had not made any investment or deposit, nor had we provided any guarantees, related to this potential joint venture investment.

Current report

Additionally, we are the primary beneficiary of the AXCS Joint Venture. As a result, the AXCS Joint Venture is consolidated.

The increase in depreciation and intangible amortization expense of approximately $2.5 million was primarily attributable to such increases related to the net increase of nine wholly-owned properties acquired after June 30, 2025, as well as additional depreciation and intangible amortization expense related to the seven properties we acquired during the three months ended June 30, 2025.

Current wording
