Exhibit 99.1

December 19, 2018

Dear Shareholder,

As 2018 draws to a close, we would like to provide you with an overview of the tremendous progress we have made on the Plan of Liquidation and Dissolution (the “Plan”) of Hines Global REIT, Inc.

Following approval of the Plan by our shareholders in July 2018, the management team immediately went to work to market key assets for sale. Using in-depth knowledge from our local market teams and macro analysis by our proprietary research group, we began selling certain assets within the portfolio to maximize the value to our shareholders.

Since July, we have sold or have entered into contracts to sell 21 properties representing 7.7 million square feet for an aggregate sale price of $2.0 billion. Once all of these pending property sales are completed, we expect to make a liquidating distribution to our shareholders.

•Timing of Liquidating Distribution: Assuming these property sales are completed in the time frame we expect, shareholders can expect to receive another liquidating distribution on or around February 15, 2019, subject to authorization by our board of directors (the “Board”). At that time, we also expect the Board to declare a new per share net asset value (“NAV”), following the completion of the annual third-party valuations.

The Board believes it is in the best interest of our shareholders to implement the following changes to ensure a strong financial position as we prepare for the ultimate liquidation and dissolution of Hines Global REIT. These changes are in line with common practice within the industry when executing a plan of liquidation and are consistent with the actions anticipated under the Plan:

•End of Monthly Distributions: We have provided reliable monthly distributions to shareholders of record since 2009.  Due to the fact that we have already sold a significant number of assets and our expectation that we will sell the remaining assets in the time frame anticipated under the Plan, we have determined to stop paying monthly distributions after December 2018.  Any future distributable income earned from the remaining properties in our real estate portfolio will simply be included in the future liquidating distributions the shareholders receive.

•Suspend Share Redemption Program (“SRP”): The Board has determined to suspend the SRP, effective on February 2, 2019, except for redemption requests related to the death or disability of the shareholder.

We are committed to maintain a thoughtful and well-timed approach to the remaining portfolio sales in order to maximize returns for shareholders. We will keep you informed of significant activities as they occur. As always, we thank you for your investment in Hines Global REIT.

Sincerely yours,

Sherri W. Schugart
