No Longer an Investment Company Under Investment Company Act of 1940

Announces Management and Board Changes

Enters New Business Management Agreement with Tremont Realty Advisors

NEWTON, Mass.–(BUSINESS WIRE)–RMR Mortgage Trust (Nasdaq: RMRM) today announced that the Securities and Exchange Commission, or SEC, has issued an order granting RMRM’s request to deregister as an investment company under the Investment Company Act of 1940, or the Deregistration Order. The issuance of the Deregistration Order enables RMRM to proceed with full implementation of its new business mandate to operate as a commercial mortgage REIT. As a commercial mortgage REIT, RMRM is focused primarily on originating and investing in first mortgage whole loans secured by middle market and transitional commercial real estate. To date, RMRM has liquidated all of its legacy investment securities and has closed five loans totaling $111.7 million in aggregate commitments.

RMRM also announced changes to its Board of Trustees and executive officers. Thomas J. Lorenzini has been appointed President and G. Douglas Lanois has been appointed Chief Financial Officer and Treasurer. Mr. Lorenzini and Mr. Lanois succeed Fernando Diaz and Brian E. Donley, respectively, who have resigned from RMRM, effective January 5, 2021.

Mr. Lorenzini is a Vice President of The RMR Group and President of Tremont Mortgage Trust (Nasdaq: TRMT). He is also a Vice President of Tremont Realty Advisors LLC, an SEC registered investment adviser and an indirect subsidiary of The RMR Group Inc. (Nasdaq: RMR). Mr. Lorenzini has over 25 years of experience in the real estate industry.

Mr. Lanois is a Senior Vice President of The RMR Group and Senior Vice President, Chief Financial Officer and Treasurer of Tremont Realty Advisors LLC. He also serves as Chief Financial Officer and Treasurer of TRMT. Mr. Lanois has over 30 years of real estate experience.

In addition, RMRM announced that Matthew P. Jordan has been appointed a Managing Trustee, effective January 5, 2021. He succeeds Jennifer B. Clark, who is resigning from her position on RMRM’s Board of Trustees, effective January 5, 2021. Mr. Jordan is also a Director and the President and Chief Executive Officer of Tremont Realty Advisors LLC as well as a Managing Trustee of TRMT. Mr. Jordan joined The RMR Group in 2012 and has been a member of the senior management team since that time. He will continue to serve as Executive Vice President, Chief Financial Officer and Treasurer of The RMR Group.

Adam D. Portnoy, a Managing Trustee of RMRM and a Managing Director, President and Chief Executive Officer of The RMR Group, made the following statement:

“We are pleased to reach this key milestone in transitioning RMR Mortgage Trust to a commercial mortgage REIT. With RMRM’s deregistration now complete and its legacy portfolio of investment securities liquidated, RMRM is well positioned to execute its business plan to invest in first mortgage whole loans secured by middle market and transitional commercial real estate. Within this new objective, RMRM has already successfully executed on five loans with a combined portfolio value of more than $110 million, and its deal pipeline is strong. We expect RMRM to fully invest its capital during the first half of 2021 and take advantage of leverage to drive increased returns to shareholders.”

RMRM has also entered into a new management agreement with Tremont Realty Advisors LLC to manage RMRM’s day-to-day operations, subject to the oversight and direction of RMRM’s Board of Trustees. Concurrent with entering this new management agreement, RMRM’s investment advisory agreement with RMR Advisors LLC was terminated. Both RMRM and TRMT are commercial mortgage REITs that are managed by Tremont Realty Advisors LLC. More information concerning the terms of the new management agreement will be provided in a Current Report on Form 8-K to be filed by RMRM with the SEC by January 11, 2021, which will include a copy of the agreement filed as an exhibit to that report.
