Item 8.01. Other Events.

The agreement governing our $450 million secured credit facility, or our credit agreement, requires us to maintain collateral properties with an aggregate appraised value of at least $1.09 billion, and allows Wells Fargo Bank, National Association, as administrative agent under our credit facility, or the Administrative Agent, to periodically reappraise the collateral properties. On June 23, 2023, we received notice from the Administrative Agent that the reappraised value of the 61 medical office and life science properties securing our credit facility had declined from $1.34 billion to $1.05 billion, below the $1.09 billion threshold required under our credit agreement. Failure to meet the required threshold constitutes a non-monetary event of default under our credit agreement. The appraised values of the collateral properties securing our credit facility declined 22% since they were last appraised in January 2021.

We are currently negotiating a limited waiver with the Administrative Agent and requisite lenders under our credit facility to waive the event of default and to decrease the required appraised value of the collateral properties through September 30, 2023, the outside closing date for our previously disclosed pending merger with Office Properties Income Trust, or OPI, at which time our credit facility will be fully refinanced.

 Because we are not currently in compliance, and have not been in compliance for over two years, with our debt incurrence covenants, we cannot issue any new debt or refinance expiring debt. We believe that the earliest we may be in compliance with our debt incurrence covenants is mid-year 2024, which is after $700 million of indebtedness becomes due in the first half of 2024. Our financial constraints are among the primary reasons that our Board of Trustees has unanimously recommended that our shareholders vote in favor of the pending merger with OPI.

The foregoing description of certain terms of our credit agreement is not complete and is qualified in its entirety by reference to the full text of our credit agreement, a copy of which is incorporated by reference into this Current Report on Form 8-K as Exhibit 10.1.

Warning Concerning Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws. Also, whenever we use words such as “believe”, “expect”, “anticipate”, “intend”, “plan”, “estimate”, “will”, “may” and negatives or derivatives of these or similar expressions, we are making forward-looking statements. These forward-looking statements are based upon our present intent, beliefs or expectations, but forward-looking statements are not guaranteed to occur and may not occur. Actual results may differ materially from those contained in or implied by our forward-looking statements as a result of various factors. For example: (a) we are currently negotiating a limited waiver with the requisite lenders under our credit facility to waive the event of default and to decrease the required appraised value of the collateral properties securing our credit facility through September 30, 2023; however, we may be unable to reach agreement with the lenders on such waiver on acceptable terms or at all. Further, we may fail to comply with the terms of such waiver or other requirements under our credit facility in the future; (b) we believe the earliest we may be in compliance with our debt incurrence covenants is mid-year 2024; however, our ability to comply with our debt incurrence covenants is subject to various factors, some of which are beyond our control, such as market conditions; and (c) the closing of our merger with OPI is subject to the satisfaction or waiver of closing conditions, some of which are beyond our control, and we cannot be sure that any or all of these conditions will be satisfied or waived; accordingly, the merger may not close on the contemplated terms or at all or it may be delayed, and if the merger does close, we may not realize the benefits from the merger that it currently expects, and our credit facility may not be fully refinanced when expected or at all.

The information contained in our periodic reports filed with the Securities and Exchange Commission, or SEC, including under “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” or incorporated therein, also identifies important factors that could cause our actual results to differ materially from those stated in or implied by our forward-looking statements. Our filings with the SEC are available on the SEC's website at www.sec.gov.

You should not place undue reliance upon any forward-looking statements. Except as required by law, we do not intend to update or change any forward-looking statements as a result of new information, future events or otherwise.

Important Additional Information About the Merger

This Current Report on Form 8-K may be deemed to be solicitation material in respect of the proposed merger between us and OPI. In connection with the proposed merger, OPI filed a registration statement on Form S-4 with the SEC, containing a joint preliminary proxy statement/prospectus of us and OPI. We and OPI intend to file a definitive joint proxy statement/prospectus. The proposed transaction involving us and OPI will be submitted to our and OPI’s shareholders for their consideration at special meetings of shareholders to be held on August 9, 2023. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, INVESTORS ARE URGED TO CAREFULLY READ THE REGISTRATION STATEMENT, THE JOINT PROXY STATEMENT/PROSPECTUS AND ANY OTHER DOCUMENTS THAT ARE FILED OR WILL BE FILED WITH THE SEC IN CONNECTION WITH THE MERGER OR INCORPORATED BY REFERENCE IN THE REGISTRATION STATEMENT AND JOINT PROXY STATEMENT/PROSPECTUS BECAUSE THEY CONTAIN OR WILL CONTAIN IMPORTANT INFORMATION ABOUT US, OPI AND THE MERGER. When available, the relevant portions of the joint proxy statement/prospectus will be mailed to our and OPI’s shareholders. Investors will also be able to obtain copies of the registration statement and the joint proxy statement/prospectus and other relevant documents (when they become available) free of charge at the SEC’s website (www.sec.gov). Additional copies of documents we file with the SEC may be obtained for free on our Investor Relations website at www.dhcreit.com/investors or by contacting our Investor Relations department at 1-617-796-8234. In addition to the registration statement and joint proxy statement/prospectus filed or expected to be filed, we file annual, quarterly and current reports and other information with the SEC. Our filings with the SEC are also available to the public from commercial document-retrieval services and at the website maintained by the SEC at www.sec.gov.

Participants in the Solicitation

We and certain of our trustees and executive officers, OPI and certain of its trustees and executive officers, and The RMR Group LLC, our and OPI’s manager, and its parent and certain of their respective directors, officers and employees may be deemed to be participants in the solicitation of proxies from our and OPI’s shareholders in connection with the merger. Certain information regarding these trustees, executive officers, directors, officers and employees and a description of their direct and indirect interests are and will be set forth in the registration statement and the joint proxy statement/prospectus when filed with the SEC by us and/or OPI. Information about our trustees and executive officers is also included in the proxy statement for our 2023 annual meeting of shareholders, which was filed with the SEC on April 20, 2023.
