SmartStop Self Storage REIT Announces Pricing of Upsized Offering of Common Stock

LADERA RANCH, Calif. — SmartStop Self Storage REIT, Inc. (“SmartStop”) (NYSE: SMA), a self-managed real estate investment trust and a premier owner and operator of self-storage facilities in the United States and Canada, announced the pricing of an underwritten public offering of 8,150,000 shares of its common stock, par value $0.001 per share, at a public offering price of $37.00 per share, in connection with the forward sale agreements. The offering was upsized from the previously announced offering size of 7,000,000 shares of common stock and is expected to close on November 12, 2026, subject to customary closing conditions.

J.P. Morgan, Wells Fargo Securities, KeyBanc Capital Markets, BMO Capital Markets and Truist Securities are acting as joint book-running managers for the offering. Evercore ISI, National Bank of Canada Capital Markets, RBC Capital Markets, Scotiabank, Cantor, Baird and Raymond James are acting as bookrunners for the offering. M&T Securities, BTIG and Stifel are acting as co-managers for the offering.

In connection with the offering, SmartStop entered into forward sale agreements with affiliates of each of J.P. Morgan and Wells Fargo Securities (the “forward purchasers”) with respect to 8,150,000 shares of SmartStop’s common stock.

The underwriters may also purchase up to an additional 1,222,500 shares of SmartStop’s common stock within 30 days from the date of the prospectus supplement relating to the offering. If the option to purchase additional shares of SmartStop’s common stock is exercised, SmartStop expects to enter into one or more additional forward sale agreements with the forward purchasers in respect of the number of shares of SmartStop’s common stock that are subject to exercise of the option to purchase additional shares.

In connection with the forward sale agreements and any additional forward sale agreements, the forward purchasers (or their respective affiliates) are expected to borrow from third parties and to sell to the underwriters an aggregate of 8,150,000 shares of SmartStop’s common stock that will be sold in this offering (or an aggregate of up to 9,372,500 shares of common stock if the underwriters’ option to purchase additional shares of common stock is exercised in full). However, a forward purchaser (or its affiliate) is not required to borrow and sell such shares if, after using commercially reasonable efforts, such forward purchaser (or its affiliate) is unable to borrow such shares, or if borrowing costs exceed a specified threshold or if certain specified conditions have not been satisfied. If a forward purchaser (or its affiliate) does not deliver and sell all of the shares of SmartStop’s common stock to be sold by it to the underwriters, SmartStop will issue and sell to the underwriters a number of shares of its common stock equal to the number of shares that such forward purchaser (or its affiliate) did not deliver and sell, and the number of shares underlying the relevant forward sale agreement or additional forward sale agreement will be decreased by the number of shares that SmartStop is required to issue and sell.

Pursuant to the terms of the forward sale agreements and any additional forward sale agreements, and subject to its right to elect cash or net share settlement, which right is subject to certain conditions, SmartStop intends to issue and deliver, upon physical settlement of the forward sale agreements and any additional forward sale agreements, an aggregate of 8,150,000 shares of common stock (or an aggregate of up to 9,372,500 shares of common stock if the underwriters’ option to purchase additional shares is exercised in full) to the forward purchasers in exchange for cash proceeds per share equal to the applicable forward sale price, which will initially be the public offering price, less underwriting discounts and commissions, and will be subject to certain adjustments as provided in the forward sale agreements. SmartStop expects to physically settle the forward sale agreements and any additional forward sale agreements on one or more dates specified by SmartStop occurring no later than September 30, 2028.

SmartStop will not initially receive any proceeds from the sale of shares of its common stock by the forward purchasers (or their affiliates). SmartStop intends to use any proceeds it receives upon settlement of the forward sale agreements, together with proceeds from the physical settlement of the forward sale agreements entered into in connection with its “at-the-market” program, to fund its pending investments, including its investment in a Canadian joint venture fund and its pending acquisitions, repay its revolving credit facility, repay its Canadian term loan and for general corporate purposes, including its potential investments.

The offering of the common stock is being made pursuant to SmartStop’s effective shelf registration statement filed with the Securities and Exchange Commission (the “SEC”). A final prospectus supplement and accompanying prospectus relating to the offering will be filed with the SEC and will be available on the SEC’s website at www.sec.gov.
