Strategic Storage Trust II, Inc. Announces Estimated Per Share Value of $10.66

LADERA RANCH, CA – June 27, 2019 – Strategic Storage Trust II, Inc. (“SST II”) announced today that its board of directors has approved an estimated per share net asset value (“NAV”) of its Class A common stock and Class T common stock of $10.66, calculated as of March 31, 2019. Previously, the board approved an estimated NAV of $10.65 calculated as of December 31, 2017.

“We are pleased to announce the updated net asset valuation of Strategic Storage Trust II, Inc., inclusive of the Strategic Storage Growth Trust acquisition,” said Michael McClure, President of SST II. “The institutional quality of our self storage portfolio, paired with the growth potential of the SSGT properties,  has maintained NAV while also growing revenues and operating income.”

On June 26, 2019, SST II’s board of directors approved the estimated per share NAV of $10.66 based on the estimated value of SST II’s assets less the estimated value of its liabilities, or net asset value, divided by the number of shares outstanding on an adjusted fully diluted basis, calculated as of March 31, 2019.

Robert A. Stanger & Co., Inc. (“Stanger”), an independent third party valuation firm, was engaged to provide valuation services of SST II’s assets and liabilities, including 112 of SST II’s self storage properties. One additional property was valued at its current contractual sales price. Upon the nominating and corporate governance committee’s receipt and review of Stanger’s appraisal report and net asset value report, the committee determined that an estimated value per share of $10.66, was reasonable and recommended to the board that it adopt $10.66 as the estimated value per share for the SST II’s Class A shares and Class T shares.

SST II acquired its 113 real estate assets for approximately $1.2 billion and invested approximately $19.5 million subsequent to purchase. The total estimated value of the properties was approximately $1.4 billion, representing an approximate 15.3% increase in the total value over the aggregate purchase price.

The appraisals were performed in accordance with the Uniform Standards of Professional Appraisal Practice (USPAP), the real estate appraisal industry standards created by The Appraisal Institute, as well as the requirements of the state where each real property is located.

The valuation was determined in compliance with the Investment Program Association’s practice guideline regarding valuations of publicly registered non-listed REITs (“IPA guidelines”). Consistent with the IPA guidelines, the valuation does not include a portfolio premium that may reasonably be expected to accrue in a typical real estate valuation process conducted for transaction purposes, nor does it reflect an enterprise value.

For a full description of the methodology and assumptions used to determine the estimated per share NAV and the limitations of the estimated per share NAV, please see SST II’s Current Report on Form 8-K that was filed with the U.S. Securities and Exchange Commission on June 27, 2019.
