Strategic Storage Trust VI, Inc. ("SST VI" or the "Company"), a publicly registered non-listed real estate investment trust sponsored by SmartStop Self Storage REIT, Inc., today announced that its board of directors (the "Board") has approved an estimated net asset value ("NAV") per share of $10.00 for its Class P, Class A, Class T, Class W, Class Y and Class Z common stock, calculated as of September 30, 2025.

"We are pleased to reaffirm an estimated net asset value per share of $10.00," said H. Michael Schwartz, President and CEO of SST VI. "This valuation underscores the strength of our portfolio and the value of our disciplined investment strategy. Rather than chasing aggressively priced acquisitions during the post-COVID U.S. self-storage boom, we strategically shifted our capital toward high-quality opportunities in Canadian markets, where we identified more favorable pricing and compelling long-term fundamentals. We believe this prudent approach has differentiated SST VI and positioned the portfolio to create long-term value for stockholders."

The estimated per share NAV of $10.00 was approved by the Board on March 20, 2026, based on the estimated value of the Company's assets less the estimated value of its liabilities, divided by the number of shares outstanding on a fully diluted basis, as of September 30, 2025.

Valuation Process

Robert A. Stanger & Co., Inc. ("Stanger"), an independent third-party valuation firm, was engaged to assist with the valuation process. Stanger prepared both an appraisal report and a net asset value report, which included valuations of 26 wholly owned properties and five unconsolidated joint venture properties within the Company's portfolio. Based on Stanger's analysis, the estimated NAV per share range was $8.30 to $10.76, with an approximate midpoint of $9.74. The Company's nominating and corporate governance committee reviewed the reports and recommended that the Board adopt $10.00 as the estimated NAV per share, which is slightly above the midpoint. The Board made this determination based upon its assessment of the Company's portfolio, the growth remaining in various properties, and the estimated range of values provided in the Stanger Report. The estimated NAV was calculated in accordance with the Institute for Portfolio Alternatives Practice Guideline 2013-01 for publicly registered non-listed REITs.

As of September 30, 2025, the Company's estimated NAV was approximately $273.2 million, compared to approximately $226.6 million as of March 31, 2024.

Portfolio Overview

SST VI's portfolio consists of a diversified mix of stabilized and growth self-storage assets across the United States and Canada, including wholly owned properties and joint venture investments. The Company continues to benefit from strong operational performance and strategic asset management initiatives designed to enhance long-term stockholder value.

Important Information Regarding Estimated NAV

The estimated NAV per share is based on several assumptions and estimates that may not prove to be accurate or complete. The valuation is not audited and does not represent the fair value of the Company's assets and liabilities in accordance with generally accepted accounting principles (GAAP), nor does it represent the amount at which shares would trade on a national securities exchange or the amount a stockholder would realize in a liquidity event.

For a full description of the methodology, assumptions and limitations of the estimated NAV per share, please refer to the Company's Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on March 23, 2026.
