Exhibit 99.2

November 10, 2020

Dear Stockholder:

We are pleased to announce that  Strategic Storage Trust IV, Inc. (“SST IV”) has entered into an agreement and plan of merger (“Merger Agreement”), whereby SST IV would be acquired by a subsidiary of SmartStop Self Storage REIT, Inc. (“SmartStop”) in a $370 million all-stock transaction (the “Merger”). Concurrent with this announcement, SST IV and SmartStop issued a joint press release describing the Merger and the related transactions, a copy of which is attached to this stockholder letter.

The proposed transaction would give SST IV stockholders 2.1875 shares of SmartStop’s common stock for every 1 share of SST IV’s common stock owned, which represents a $0.10 per share premium to SST IV’s most recent estimated Net Asset Value (NAV) calculation, when using SmartStop’s most recent estimated NAV of $10.40 per share. This price also represents a premium to the offering price of SST IV’s shares, net of offering expenses. The transaction values SST IV at approximately $370 million, based on September 30, 2020 share counts and debt principal balances outstanding, and using the agreed exchange ratio and SmartStop’s estimated NAV per share of $10.40. Based on the exchange ratio of 2.1875 set forth in the merger agreement, the total annual distribution per share of SST IV common stock will be approximately $0.60 compared to the equivalent of $0.71 prior to the Merger.

Assuming the Merger is consummated in accordance with the terms in the Merger Agreement, SmartStop will acquire all of the real estate owned by SST IV, creating a combined company consisting of 136 owned self storage facilities located in 18 states and Ontario, Canada, comprising approximately 90,000 self storage units and 10.3 million net rentable square feet.

Exhibit 99.2

The Merger has been unanimously approved by the special committee of SST IV’s board of directors, which was formed to evaluate this transaction and is composed exclusively of independent directors, and the entire board of directors of SST IV, with the assistance of separate financial advisors and legal counsel. The Merger is expected to close in the first half of 2021, subject to certain closing conditions, including approval by our stockholders. After the closing of the merger, the expected ownership of the combined company is estimated as follows: approximately 64% existing SmartStop stockholders, approximately 25% current SST IV stockholders, and approximately 11% management, using September 30, 2020 share and operating partnership unit counts.

In the first quarter of 2021, we expect to send a joint proxy statement/prospectus, which will contain relevant and important information about the Merger and will be used to solicit your vote on the transaction. Your response and approval is greatly appreciated, as it is critical to a timely closing of this transaction. For more information on the Merger, please see the attached press release, as well as SST IV’s Current Report on Form 8-K filed on November 10, 2020.

Suspension of the Distribution Reinvestment Plan

During the pendency of the Merger, SST IV will temporarily suspend its distribution reinvestment plan (DRP) commencing November 20, 2020, and DRP participants will receive future distributions, beginning with October 2020’s earned distribution, in cash, as follows:

Upon the closing of the Merger, your current DRP preference with SST IV will carry over to your future investment in SmartStop. That means that investors in SST IV who, previous to November 20, 2020, were reinvesting their distributions through the DRP will revert back to reinvesting distributions through SmartStop’s DRP following the closing of the Merger. The SmartStop board of directors has historically declared monthly distributions totaling $0.60 per share per year, however, there can be no assurance that SmartStop will continue to declare monthly distributions in this amount in the future.

Stockholders with questions about their outstanding shares should contact investor relations at (866) 418-5144. Additionally, if you need to update your address in order to receive distribution payments as noted in bullet #2, please contact investor relations.

We are truly excited about the future, as we believe that combining SST IV and SmartStop bolsters our commitment to growth and maximizing stockholder value. On behalf of the SST IV board and the entire management team, thank you for your investment in SST IV.

Continued successes,
